Somatic intervention examples
What Is Somatic Therapy? Definition And Examples
Until recently, western medicine treated mind and body separately, contrary to the somatic approach. A new emphasis on the mind-body connection has emerged recently as doctors and therapists make new advances, with somatic therapy being an example. This kind of approach uses a body-centered approach to connect the mind and body. Many online therapists have been practicing somatic therapy with their patients, as well. Let's explore its benefits and definition.

What Is Somatic Therapy?
The APA definition of somatic experiencing therapy is “the treatment of mental disorders by physical methods that directly influence the body, such as the administration of drugs (pharmacotherapy) or the application of a controlled, low-dose electric current (electroconvulsive therapy).”
When we talk about somatic therapy as a form of talk psychotherapy, we’re generally talking about a specific type called somatic experiencing. As a form of body psychotherapy, the aim of somatic experiencing therapy is to get in touch with your body and become aware of suppressed emotions in session.
Autonomic Nervous System
Therapists who use somatic experiencing therapy understand that emotional traumas of all kinds can cause instability in your autonomic nervous system (ANS). Data and scientific research shows that our body's natural response to threats is vital for dangerous situations. Short term, this is positive, but your nervous system can subsequently become stuck in a state of pent up tension, arousal, or shutdown. Needless to say, being in one of these states of tension long-term doesn’t feel the best. If you've experienced trauma, you may feel both the emotional and physical effects of that response. Trauma symptoms may manifest in body aches, headaches, nausea, and other symptoms. Note that the term “trauma” is used vastly in this context and can range from trauma caused by a traumatic event (I.E. physical illness, abuse, a car accident, etc) to trauma - or impact - of a mental health condition such as depression.
Balancing Your ANS
Therapists can use somatic therapy techniques to get your ANS back into balance. Many people notice that both physical and emotional or psychological symptoms of disorders such as depression, chronic pain, and post-traumatic stress disorder (PTSD) improve.
This approach doesn’t always look the same across physical therapies, however. A wide array of physical somatic therapy techniques can be used in conjunction with standard talk psychotherapy. This also varies in the United States and around the world. Your therapist may specialize in one of these physical sensation techniques, or they may use more than one to suit your specific issue or needs.
The healing journey will vary from person to person. We all go through rough patches, and they all have the potential to impact us in various ways. To better express what somatic experiencing may entail, let’s take a look at some common techniques used in this treatment and how they work to heal our emotional health challenges by releasing pent up tension.
Techniques And Examples
From ancient Eastern counseling practices to recently developed Western techniques, beneficial somatic therapy approaches can be found in nearly every culture. The following list is just a sampling of the techniques that can be used sensorimotor psychotherapy.
- Breathing exercises
- Vocal work
- Sensory awareness
- Body-mind centering
- Dance
- Kinetic awareness
- Martial arts
- Ayurveda
- Yoga
- Massage
- Postural integration
- Reiki massage
- Acupressure
- Meditation
It’s important to note that you’re in control of your experience with somatic therapy. Before you start working with a somatic therapist, you can speak with them about what techniques and approaches they like to use to see if you’re a good fit. As for how these techniques work, they all have one thing in common, which is that they require you to connect with your body.
Applications
Often, somatic therapy is used to help people who have experienced trauma or abuse. People with PTSD in particular can benefit from these types of somatic therapy techniques. However, it can also be effective for people experiencing other medical issues, like depression, anxiety, substance use disorder, relationship issues, and other mental health disorders.
Restoring Physical Balance
Somatic therapy can be especially helpful for any disorder that physically or energetically impacts an individual, like digestive disorders. Some somatic therapies help treat specific physical diseases (both inherited and acquired), and it may also help with life-threatening illnesses like cancer, digestive disorders, and cystic fibrosis. Remember that what’s considered somatic therapy is vast and that somatic experiencing is likely what you’re looking for if you’re seeking a somatic or body approach to talk therapy.
Benefits
Somatic therapy psychology encompasses a range of mind-body therapies and relies on a connection between mental and physical processes.
If you look at the signs and symptoms of mental health conditions such as PTSD or depression, you’ll notice that they include physical symptoms. It can help you get in touch with and address physical symptoms you may or may not have even noticed in the past as well as where those symptoms are coming from and the emotions or distress that may show up along the side, allowing you to feel emotional, psychological, and physical relief from pain.
Increase Sense Of Self
If you pursue somatic therapy to support your recovery from past trauma and other similar concerns, your therapist will help you reframe your traumatic experiences and build distress tolerance so that you can overcome their negative effects on your mind and body. You can also learn to have a greater and more positive sense of self. Your self-confidence may grow as you reduce your worrying, gain a sense of hope, improve your ability to concentrate, and become calmer and more resilient to stress.
Getting In Tune With Your Body
From a physical perspective, somatic therapy as a treatment option helps you get in tune with your body and where your feelings show up in your body.
You may find that your physical pain or discomfort decreases with somatic therapy and, in some cases, that you’re able to be more active and have more regular movement. It can also improve sleep, too.
Understanding Your Body's Responses
Paying attention to your body can be intimidating or even scary for some people. Doing so in a safe, confidential setting can be advantageous for nearly anyone. Many of us learn to turn away from or ignore how our body feels to cope, especially those of us who have encountered trauma or who experience high-stress levels or big emotions. A person's thoughts and feelings are powerful. Talk therapy, broadly speaking, is one of the leading treatments for several different conditions and concerns, and adding somatic therapy practices can enhance the outcome of talk therapy for other medical issues even more.
Integrating Somatic Practices Into Talk Therapy
Talk therapy is an umbrella term of sorts, encompassing a vast majority of client-therapist, client-psychologist, or client-counselor relationships.
Talk therapy that integrates somatic practices and physical therapies can help individuals:
- Learn to embrace life again or improve your quality of life during or after recovery from or management of a physical illness or trauma.
- Gain a better perspective on one’s emotional, psychological, and social health as well as how these things connect with the physical body and physical sensations.
- Learn relaxation techniques or mind body exercises for self regulation to help reduce tension and cope with stress more effectively.
- Improve and develop social skills and reduce any isolation that occurred as a result of trauma, physical pain, or illness.
- Decide how you want to form your life now and make positive steps toward your future. It can help you move through any roadblocks you might have and move forward with more clarity, skills, and confidence. As the saying goes, today is the first day of the rest of your life!

These specific interventions help effectively address the emotional health challenges happening in a person's mind in a way that combines mindfulness and bodily sensations.
10 Somatic Interventions Explained — Integrative Psychotherapy Mental Health Blog
As a somatic therapist who helps clients heal in mind, body and spirit, I often get asked about this method of treatment.
What is somatic psychotherapy?
Somatic Psychotherapy is a term that’s been used more frequently over the past few years as scientific research has proven that, as humans, we store memories, experience and emotions on a cellular level. Which means, it’s not “all in your head”; rather, our bodies hold data as well.
This is why many people express a feelings of “body anxiety” even in the absence of anxious “thoughts”. It’s also why you may find yourself not feeling very safe in your own skin on certain occasions, times of year or in certain environments, even if there is no “apparent” reason. Often, your body is reminded of something {even when your mind does not} and is sending an alert, a pause, or even a danger signal.
A body based therapy to help you heal on a cellular level
Initially, somatic therapies were created to help trauma survivors finally experience relief from their trauma symptoms such as flashbacks, difficulty sleeping, dysregulated eating patterns and chaotic relationships and lifestyles.
However, over the last number of years, somatic therapy has been effective in helping individuals who struggle with all kinds of stressors and has been effective in helping them finally experience relief.
Areas such as : relationship, intimacy, those seeking a feeling of security, wanting to feel trust, over/under achievers, parenting skills, managing anxiety, working though depression and other emotional difficulties.
Accessing the Root of the Issue- an Integrative Approach to Healing
Therapies which focus on talking about “tough stuff”, learning skills or solely rely on the psychodynamic relationship without somatic , mind-body awareness or trauma interventions can be helpful up until a certain point.
Sometimes, clients are “doing” all the right things, but somehow aren’t feeling relief. This often happens when the therapy emphasizes focuses on “brain-based issues”, often assuming the mind and thinking style to be causing psychological distress. However, many times, it isn’t “just in your head”, and it’s not always related to an anxious, depressive or nervous wracking thought that is the cause of the problem.
When your distress is carved on your body; not in your mind.
In certain instances, the brain and body have been wired {based on experiences], leaving the body with unconscious, deeply-rooted beliefs that are not accessible by cognitive approaches such as “I am bad” , “I’m alone”, or “I won’t ever heal”, many times, the person may not even be aware of the beliefs they carry until confronted with a struggle related to it.
Because of this, Dr. Peter Levine (founder of Somatic Experience) and Dr. Pat Ogden (founder of Sensorimotor Psychotherapy) have researched, introduced, and trained many therapists in somatic approaches, utilizing an integrative whole-body approach to psychotherapy, to help clients access the body-based beliefs and release experiences that have been held on the body. These approaches have helped clients experience long term relief.
Somatic psychotherapy is a therapeutic approach which engages the body awareness as a powerful tool and intervention in therapy.
Somatic approaches are used to engage the relationship between mind, body, brain, and behavior. Somatically trained therapists use interventions to help calm their clients’ nervous system, and create more ease in the healing process.
Curious to know more? Here are some key concepts used in somatic psychotherapy.
1} Developing Somatic AwarenessIn somatic therapy, we educate clients about what body awareness is, and how to cultivate body awareness in and around your body.
This is a prerequisite to creating change on a cellular level. We begin by identifying areas of tension and areas of constriction, as well as thoughts, feelings and behaviors that promote a feeling of calm and safety, and bring these to conscious awareness. We may practice something small such as softening a “hunched” back to a more straightened posture, to begin working towards body alignment.
By focusing on, and amplifying the sensations in your body, you begin to deepen your healing experience and allow for change that you can “feel” in your skin.
2} ResourcingResourcing refers to the way we strengthen our sense of stability and safety in the world. In session, before beginning deeper work, we identify the resources you may have. Often we will look at significant people, relationships, ego strengths, experiences, times and places that strengthen a sense of safety and choice. Sometimes, this is a practice of coming up with a “secure space” - which can be real or imaginary, where we expand on a space that give you a feeling of peace, ease and calm.
We also resource “protective figures”, “wise figures”, and “nurturing figures” by bringing to mind individuals who give you a sense of strength, empowerment and trust- and from there we may ask your body; for example: “ how does it feel to be in your skin when you bring up the image of those people who are protective figures in your life?”
We “download” the sensations, thoughts and feelings associated with feel-good experiences so the mind + body can come back to these resource states later when trauma or anxiety work gets tiring. The resourcing provides as an anchor to replenish energies.
3} Grounding in the Here-And-NowGrounding refers to our ability to experience our full selves as connected and “embodied”.
The concept of grounding is at the root of mind-body focused interventions. Alexander Lowen, developer of bioenergetics, introduced grounding as a concept in which we can live life, fully experiencing ourselves- connected in the world around us.
We use grounding tools to help calm and regulate our nervous systems when we are feeling overly activated or triggered, as grounding helps sooth and settle.
Often I use a 4 Elements Exercise where we get in touch with the elements around us; earth, air, water and fire.
4} Using Descriptive Language
Today’s somatic focused therapy approach is all about getting curious, getting descriptive and staying close to the experience that’s happening in and around your body. Tension, anxiety and trauma memories get processed as long as you can track, contact, describe and allow the experience to move through you.
For example, you’re angry at something that’s happened, but you don’t want to stay angry and irritated. You can get descriptive to meet your body experience, to help yourself move through it.
You may begin with some words such as, “It feels like a raging fiery feeling welling up in my chest….
”. As you stay with the sensations, and follow what happens next, you’ll notice the anger moves, and how it slowly shifts as you focus on the descriptive body sensation instead of the details of the upsetting event. You can use descriptive language as a method to deepen whatever you’re experiencing. Some descriptive words are: warmth, cold, tingly, sharp sensation, numb, dull pressure, ease, spinning, lifting, swirling, or calming.
Movement is a natural way for the body to move through difficult experiences, insecurities, past traumas and and intense emotions. Movement is a natural way to help strengthen your abilities to show up, be connected to others and feel more confident.
Movement helps us tap into our innate ability to heal the stories that our bodies hold.
If you take some time, you’ll notice how each of us carries stories and beliefs which impact how we interact with others and the people around us.
Our gestures, postures, voice volume and presence in the room communicates what we believe about ourselves, what we expect, or what we’ve experienced in the past.
In session, we would use movement to help you move through something that is coming up. For example, if you have an urge to hide behind other people, or to speak really quietly, we would notice that urge, and stay with it, allowing you to take on a physical movement to represent “the need to hide”. You might crouch down or look away. As you do that, you may have a thought such that is related to this urge, such as “its not safe to talk, or I won’t be heard” or “I actually have something important to say”. You may also have an image come up that is matched with when you learned you needed to “hide”. All of this is data that is easier to access, process and release when combined with movement.
6} Co-Regulation & Self RegulationCo-regulation refers to the way we calm ourselves down when we are connecting to someone else.
In attachment focused therapies, the therapist uses her/himself to use mirror neurons to help the stressed or disconnected client calm down. When we are connect to another person’s sense of warmth, care and stability, we are able to better regulate our emotions.
Self Regulation is when we develop our own tools to calm ourselves down on our own. We all need a combination of both; soothing we get from others as well as our own abilities to self regulate when needed. Self regulation tools are taught to help you move through big emotions, and co-regulation techniques are used as well, in the therapy room, as well as teaching you how to utilize close relationships to help you regulate.
Emotional Regulation is also a vital ingredient in parenting because we teach our children how to regulate by how we help them regulate, and in turn, they learn how to self-regulate based on the co-regulation they got from the parent-child bond.
Living a regulated life is one of the biggest accomplishments, because when we are regulated we are able to live more deeply, love more fully and experience the sweetness of daily pleasures.
Trauma, panic, fear, terror, anger, frustration and depression all express via sensations in the body. We can feel overheated, trapped, frozen, disconnected or completely lost. Those kinds of experiences and emotions won’t move when you dive into them head-first, as you run the risk of flooding yourself and re-traumatizing your mind and body. ‘
When we approach healing from a body centered place, we do so with appropriate pacing and tracking so that the body can tolerate the discomfort, and properly release the emotions needing to be released. Two common words used regarding pacing and tracking are titration and pendulation.
Titration is a process in which we experience small levels of distress at a time, with the focus being to release, and “discharge” the tension from the body.
Pendulation is what is used to achieve titration, as pendulation is when you pendulate your focus between stressful content and something completely non-stress related {calming/soothing content}.
You may do this by focusing on a stressful sensation that comes up when you begin processing something important. You then slowly oscillate to a resource such as the trust you have in a relationship in your life, or a belief that is reassuring to you. Oscillating through the two helps the body slowly tap-into and then release, at a balanced pace.
8} Act of TriumphAn act of triumph is a term Pierre Janet coined, and later, Peter Levine and Pat Ogden often use this concept in Somatic Experience and Sensorimotor work. This term is used to references a trauma or event where the body needed to engage in an act of defense or a way of protecting itself, and couldn’t.
Somatic work": helping the body re-negotiate events on a body-based level so you can experience relief.
This is because past events get trapped in the body and play themselves out with intrusive images, thoughts, tension, panic, unhealthy relationships and a feeling of sadness or despair.
For example, if you were stuck in a situation and needed to get away, but couldn’t, in somatic therapy we would help you slowly drop into the sensation of the event that happened; without going into too much talking about it - but letting the body go back to what it experienced. We then try an experiment where the body does what it needed to do- so you may move your feet as if you’re beginning to walk or run out, or reach out to someone who could have taken that part of you out of the difficult, or even dangerous, situation.
Another act of triumph may be to push against a pillow, or a wall, feeling the strength in your arms, being able to set a boundary or say “no” to whatever it is that you needed to stop at some point in the past, but couldn’t because you didn’t have the strength, it would have been dangerous or you didn’t know how.
Even though you are no longer in the situation, the cells in your body are still connected to that event, and when you engage in an act of triumph, the body often experiences a deep sense of calm and relief on a cellular level that it had not experienced by simply talking about the event.
Sequencing is the process of which the body-based tension begins to release, and it typically happens with a beginning movement, sensation that moves up or down a part of the body, or an emotion that intensifies and then slowly starts to lessen. It’s like a linking experience, where there are a few dominoes, and once the process starts, the rest of the body continues to sequence; Tension in the belly may begin moving upward to your upper body, feel like tightness in your chest and then feeling like your arms are heavy.
As you stay with it, you may notice a pulsing feeling in your throat, or a tightness in your head/ or around your forehead.
At some point, there there is often trembling, where the hands and/or legs tremble, where the tension begins leaving the body.
There are many ways the body moves through sequencing, tension can leave through the top of your head, bottom of your feet, tips of your hands or arms, but there’s an obvious moving through. Sometimes it takes a matter of seconds, and for others, it can be a few minutes.
Sequencing often also brings other forms of release; you may cry as a way of letting go emotions and sadness that you’ve been holding. You may take a deep sigh and notice an ability to breath easily, or you may feel like you’ve dropped a huge brick from your heart. Clients often express a lighter feeling after their body has properly sequenced through an event or emotional experience.
10} Boundary SettingBoundaries are a foundational piece of work when it comes to healing. When you lean into boundaries from a somatic standpoint, you will notice what kind of boundaries you are naturally setting; verbally and nonverbally.
In session we may practice saying words like “YES” or “NO” or “ stop” or “okay”, sensing what it’s like to express limits using movement, nonverbal cues as well as verbally. Setting boundaries is one of the surest ways to feel protected and steady in your skin, and in your day-to-day interactions.

0 LikesWhat is the somatic nervous system
The somatic nervous system (SNS) is a part of the peripheral nervous system responsible for all volitional movements of the body. The somatic nervous system is made up of relatively large sensory and motor nerves that conduct impulses quickly, allowing us to quickly respond to stimuli in our environment.
What is the somatic nervous system?
The somatic nervous system is under conscious control, meaning we can choose to move our muscles or not. For example, when we decide to pick up a book, our brain sends signals along the motor neurons to the muscles in the arm, telling them to contract.
The somatic nervous system can also be subject to unconscious activation. For example, when we trigger a reflex, use muscle memory, or automatically move away from a painful stimulus.
How does the SNS fit in with the rest of the nervous system?
The human nervous system is divided into the central and peripheral nervous systems. The central nervous system (CNS) consists of the brain and spinal cord. The peripheral nervous system (PNS) is made up of all the other nerves located throughout the body. Peripheral nerves connect the central nervous system to our organs, muscles, and glands. The PNS is subdivided into the somatic nervous system and the autonomic nervous system.
The somatic nervous system (SNS) is a voluntary nervous system, meaning we can choose whether to activate it. Its main duty is the conscious control of skeletal muscle movements. The SNS also deals with some involuntary movements, such as reflexes.
The autonomic nervous system (ANS) is responsible for the involuntary functions of the body, that is, it works automatically. It controls all the processes that keep us alive and functioning, such as heartbeat, breathing, and digestion. The autonomic nervous system is divided into sympathetic (fight or flight) and parasympathetic (rest and digestion).
The somatic and autonomic nervous systems often work together. For example, in bladder control: parasympathetic innervation allows urine to exit the bladder, but somatic (volitional) muscle control is required for urination.
Anatomy of the somatic nervous system
The somatic nervous system includes all nerves that innervate skeletal muscles.
These nerves originate in the spinal cord and brainstem and spread throughout the peripheral nervous system. The somatic nerves allow us to control muscle movements voluntarily, but they can also be activated without a conscious decision (such as reflexes).
The somatic nervous system includes sensory and motor neurons. Sensory neurons are afferent, meaning they send signals from the body to the brain. Efferent motor neurons do the opposite. Somatic nerve fibers are isolated by a relatively thick layer of myelin, so they conduct impulses quickly. This allows us to respond quickly to stimuli in the environment.
Brain and spinal cord
The somatic nervous system is part of the peripheral nervous system, but the central nervous system is still critical to its functioning. The brain interprets sensory input and signals motor responses to control the entire body. The motor cortex in the frontal lobe generates somatic motor impulses.
The spinal cord is a long column of nerves that runs down the back and carries messages between the brain and other parts of the body.
It is the most important relay center for somatic motor neurons and the somatic reflex arc.
Some of the nerves involved in the somatic nervous system come directly from the brain and spinal cord. They are called cranial and spinal nerves.
There are 12 pairs of cranial nerves, ten of which originate in the brainstem. These nerves receive signals from sensory organs such as the eyes and nose. The cranial nerves also voluntarily control the muscles of the head.
There are 31 pairs of spinal nerves that connect to different areas of the spine. They transmit somatosensory and volitional motor signals between the periphery and the spinal cord.
Somatic sensory neurons
Sensory neurons in the somatic nervous system have endings in muscles, bones and skin. They capture somatic sensations, that is, any sensations experienced by the body.
Somatic sensations can be exteroceptive (outside the body) or proprioceptive (inside the body). Exteroceptive somatic sensations include touch, pain, temperature, and pressure.
Proprioceptive sensations include the position of the joints and muscle tension, they help to navigate in the environment.
Somatic motor neurons
Motor neurons in the somatic nervous system innervate skeletal muscles. That is, all the muscles that we can voluntarily control. There are two main types: upper motor neurons and lower motor neurons.
Upper motor neurons originate in the cerebral cortex. They synapse with lower motor neurons in the spinal cord, which further innervate muscles. Synapses are places where nerves transmit chemical or electrical impulses to other nerves or target tissue.
Upper motor neurons
Upper motor neurons are nerve cells that transmit signals from the brain to the spinal cord. They originate in the primary motor cortex of the brain, located in the frontal lobe. The motor cortex generates signals for the voluntary control of motor actions. Upper motor neurons travel along two pathways: pyramidal and extrapyramidal.
Pyramidal tract: Most upper motor neurons pass through the medullary pyramids in the brain stem, the area that connects the brain and spinal cord. These fibers of the pyramidal tract transmit signals for all voluntary muscle movements, from wide to extremely fine.
Extrapyramidal tract: These nerve fibers do not pass through the medullary pyramids as they pass through the brainstem. Fibers in the extrapyramidal tract transmit signals about changes in voluntary movements such as speed and coordination. They also transmit signals for involuntary motor control, such as posture, and actions that become involuntary over time, i.e. muscle memory.
Lower motor neurons
Lower motor neurons are the final link of the somatic nervous system. They originate in the spinal cord and innervate the skeletal muscles of the entire body. When the lower motor neuron receives stimulation from the upper motor neuron, it causes the muscle to contract. The lower motor neurons in the somatic nervous system are composed of three types: alpha, beta, and gamma.
Alpha motor neurons: These are the most numerous lower motor neurons in the somatic nervous system. Alpha motor neurons innervate the main part of the muscle and ensure its contraction.
Gamma motor neurons: Unlike alpha neurons, gamma neurons do not cause muscle contractions. Instead, they innervate stretch-sensitive muscle fibers and tell alpha neurons to keep contracting.
Beta motor neurons: Little is known about the role of beta motor neurons. They innervate the same types of motor fibers as alpha and gamma motor neurons, so they can support the functions of the other two.
Lower motor neurons are also involved in the somatic reflex arc. Sensory nerves detect a specific stimulus and can synapse directly with lower motor neurons in the spinal cord to cause a specific muscle contraction. The reflex arc bypasses the brain, so these actions happen quickly but involuntarily. For example, pressing on the patellar tendon below the knee causes contraction and extension of the quadriceps calf muscle.
An impulse from a sensory nerve may also pass through one or more interneurons and reach a motor nerve.
How does the SNS generate traffic?
The human body contains three main types of muscles: skeletal, cardiac and smooth. Cardiac muscle makes up the heart, and smooth muscle is present in internal systems such as the digestive tract. Both are controlled by the autonomic nervous system.
The somatic nervous system controls skeletal muscle, which usually comes to mind when we think of muscles. Examples of skeletal muscles are biceps, triceps, and quadriceps.
When the lower motor neurons reach the muscle, they synapse with the muscle fibers to form the neuromuscular junction. Muscle fibers are the long, cylindrical cells that make up our muscles. Most muscle fibers are designed to create real muscle contraction. They are innervated by alpha motor neurons. Muscle fibers that do not contract are called muscle spindles, they determine muscle stretch and are innervated by gamma motor neurons.
The stages of muscle contraction from intention to action are:
- Somatosensory input tells the brain that we must move (for example, a hand is on a hot surface), or we simply decide to move (for example, we want to pick up a pencil).
- The primary motor cortex generates a motor signal.
- The upper motor neurons receive the signal and transmit it to the spinal cord.
- In the spinal cord, upper and lower motor neurons synapse.
- Lower motor neurons deliver signal to muscle fibers through neuromuscular junctions.
- The signal triggers the contraction of the muscle fibers and the muscle contracts.
- The muscle contracts and produces force to perform the intended action!
This fast process repeats every movement of our skeletal muscles many times over.
Sensory input from the muscles and joints is relayed back to the central nervous system, allowing us to control our movements and adjust them as needed.
This feedback is called proprioception and is critical because it allows us to know where our limbs are in space and how much force we are applying.
Disorders of the somatic nervous system
Damage to the somatic nervous system can occur anywhere from the motor cortex to the skeletal muscles. General terms for diseases of the somatic nervous system are motor neuron disease and peripheral neuropathy.
Symptoms often include tremors, muscle spasms and impaired motor function. Some diseases are congenital, that is, a person is born with them, or they can develop during life. Causes such as trauma, viruses, and toxins can be genetic or environmental. Causes and risk factors often remain unclear.
Examples of disorders affecting the somatic nervous system are:
- Amyotrophic Lateral Sclerosis (ALS), also called Lou Gehrig's disease
- Multiple sclerosis (MS)
- Poliomyelitis
- Herniated disc
- Radiculopathy (pinched nerve)
- Spinal cord injury
The treatment of these conditions may vary.
Some of these may involve medication, while others may require surgery. Strategies for maintaining overall somatic nervous system health include regular, moderate-intensity exercise and a diet low in fat and antioxidants.
Conclusion
The somatic nervous system is critical to the control of all volitional movements. Somatosensory nerves allow us to perceive information from our environment such as pressure, temperature and pain, as well as the position of our body. Somatic motor nerves innervate the skeletal muscles of the body to produce the appropriate motor responses.
Frequently Asked Questions
What are the responsibilities of the SNS?
The somatic nervous system provides conscious control over skeletal muscle movement. It is a division of the peripheral nervous system and includes sensory and motor neurons. It is also involved in some unconscious motor functions (eg, motor coordination, muscle memory, reflexes).
What are examples of SNS functions?
There are many examples of the somatic nervous system in action.
The somatic nervous system is responsible for the movement of skeletal muscles. Examples include walking, running, lifting weights and playing sports. The somatic nervous system also controls eye and head movements such as blinking and swallowing.
What are the main components of an SNS?
The main components of the SNS are somatosensory neurons, motor cortex, upper and lower motor neurons, and neuromuscular junctions. Somatosensory neurons send information about pressure and touch to the brain. The motor cortex generates a motor signal, which is transmitted by upper motor neurons to the spinal cord. The lower motor neurons transmit the signal from the spinal cord to the muscle, which is transmitted through the neuromuscular junction.
How can I protect my SNS?
With age, the somatic nervous system undergoes a natural decline, resulting in a decrease in sensory and motor control. This is often due to deterioration of the neuromuscular junction (NJJ). Studies show that diet plays an important role in the health of VMW.
Experiments in mouse models have shown that avoiding a high-fat diet and excess caloric intake can prevent worsening of NMJ and even reverse some of the damage.
Reactive oxygen species can also damage NMJ. These free radicals are natural by-products of several bodily processes, including muscle contraction.
Our bodies normally produce antioxidants to counteract this, but increasing your intake of antioxidants can provide additional protection to NMJ. This may include vitamin D supplements, foods rich in vitamin E (such as spinach and tomatoes), and other antioxidant-rich foods (such as dark chocolate, blueberries, pecans, and kale).
Regular moderate-intensity exercise can increase antioxidant production and prevent NMJ damage. Exhausting workouts can cause excessive production of reactive oxygen species and potentially overload the body's natural antioxidants.
Does the word "somatic" always refer to SNS?
No, "somatic" actually means "related to the body.
" The somatic nervous system got its name because it is responsible for the sensations and movements of the body. Some confusion may arise, as the word "somatic" is used in many terms that are not related to the somatic nervous system.
For example:
- Somatic cells : most of the cells that make up the body (skin, muscles, bones, nerves, etc.), as opposed to germ cells, which are reproductive cells (sperm, eggs).
- Syndromic physical disorder : A mental health condition in which a person exhibits specific physical symptoms that do not always have an explicable medical cause. Although physical symptoms may be associated with SNS, they should not be confused with SNS disorders.

ASA classification (American Society of Anesthesiologists)
ASA (American Society of Anesthesiologists) Physical Status is an assessment of the patient's condition before surgery. There are 5 classes of physical status (from a healthy patient to a patient in extremely serious condition): ASA I - healthy patient; ASA II - patient with mild systemic disease; ASA III - a patient with a severe systemic disease; ASA IV - a patient with a severe systemic disease that is a permanent threat to life and ASA V - a dying patient.
Operation for vital indications. Additional, sixth class - ASA VI , is used when ascertaining the death of the patient's brain and is used in transplantology.
Determining the physical status of the ASA is always used when examining an anesthesiologist.
