An Introduction into the Nervous System and Somatic Interventions

The human body is made up of a network of systems working to maintain balance and functionality. One of the most complex and intricate systems is the nervous system, responsible for coordinating and regulating bodily functions, processing sensory information, and even controlling thoughts and emotions. In recent years, holistic approaches to mental and physical wellness have gained traction, emphasizing the interconnectedness of the mind and body. Somatic interventions is a cornerstone of this approach, which recognizes the fundamental role the nervous system plays in our overall well-being.

The Nervous System: The nervous system is an intricate network of cells, nerve fibers, and structures that work together to transmit signals throughout the body. It is made up of two main components: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consist of the brain and spinal cord, with the spinal cord acting as a channel for nerve signals between the brain and the rest of the body. The PNS includes all the nerves that extend from the CNS to the rest of the body and can be broken down into two subsystems: the somatic nervous system and the autonomic nervous system.

Somatic Nervous System: the part of the PNS that controls voluntary actions and transmits sensory information (from skin, muscles, and joints) to the CNS. It is also responsible for skeletal and muscle movement. A

Autonomic Nervous System (ANS): the part of the PNS that controls involuntary bodily functions such as heart rate, digestion, respiratory rate, and other vital processes that occur without conscious effort. The autonomic nervous system is further broken down into the sympathetic and parasympathetic branches. The sympathetic part of the ANS is otherwise known as the “fight or flight” response, which prepares the body for action in times of intense stress or danger. The parasympathetic part of the ANS is otherwise known as the “rest and digest” response, which facilitates a sense of calm, relaxation, and recovery.
