An Introduction to the Nervous System

The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. Primarily, it is divided into two main parts - the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).

Understanding the Somatic Nervous System

The somatic nervous system is a part of the peripheral nervous system that coordinates the body's voluntary motor control, essentially controlling the movements that we can consciously regulate.

Comprehending the Sympathetic Nervous System

The sympathetic nervous system, also under the peripheral nervous system's umbrella, prepares the body for the 'fight or flight' response in stressful situations. It's largely responsible for the automatic response of our body under threatening circumstances.

Distinguishing the Somatic vs Sympathetic Systems

When comparing the somatic vs sympathetic systems, the key differences lie in their function and control. While the former is voluntarily controlled and involves sensory and motor functions, the latter is not manually controlled and is responsible for the body's uncontrolled reactions to stress.

Role of Both Systems in Trauma

Both the somatic and sympathetic nervous systems play significant roles when an individual experiences trauma. Trauma can lead to an overactivation of the sympathetic nervous system, leading to a heightened 'fight or flight' response. Conversely, trauma-informed therapies often target the somatic system to help individuals voluntarily control their bodily responses better.

The Impact of Trauma on the Nervous Systems

Trauma can have long-term effects on both the somatic and sympathetic nervous system, leading to conditions such as anxiety, insomnia, and post-traumatic stress disorder (PTSD). Understanding how each system functions can help develop effective treatment plans for individuals dealing with trauma.

Trauma-Informed Approaches for Therapy

With a deeper understanding of how trauma affects both the somatic and sympathetic nervous system, professionals can employ trauma-informed approaches to help individuals. These may include biofeedback, somatic experiencing, and cognitive-behavioral therapy among others.

Frequently Asked Questions

  1. What is the role of the sympathetic system in trauma?The sympathetic system primes the body's 'fight or flight' response. In trauma, this system can become over-activated, leading to panic attacks, hyperarousal, or other physical symptoms.

  2. How does the somatic nervous system respond to trauma?The somatic system may also be affected by trauma, leading to symptoms like tension, trembling, or trouble breathing. Therapy can help individuals learn to better control this system and manage these symptoms.

  3. Can understanding the somatic vs sympathetic systems help in trauma recovery?Yes, understanding the individual and combined function of these systems can contribute significantly to trauma recovery. It can help individuals understand their responses better and also help therapists develop more effective treatment plans.

  4. How can I keep my nervous systems healthy?Regular exercise, a balanced diet, adequate sleep, and regular check-ups with your healthcare provider can help maintain a healthy nervous system.


We hope this comprehensive guide brings clarity to the topic of somatic vs sympathetic in the context of trauma-informed training. With increasing awareness of trauma's impact on the nervous systems, such insight is crucial for improving mental health outcomes.
