nervous system disorders
The sympathetic nervous system (SNS) is one of the two main divisions of the autonomic nervous system, the other being the parasympathetic nervous system. (The enteric nervous system (ENS) is now usually referred to as separate from the autonomic nervous system since it has its own independent reflex activity.)The autonomic nervous system functions to regulate the body’s unconscious actions. The sympathetic nervous system’s primary process is to stimulate the body’s fight-flight-or-freeze response. It is, however, constantly active at a basic level to maintain homeostasis hemodynamics. The sympathetic nervous system is described as being antagonistic to the parasympathetic nervous system which stimulates the body to “feed and breed” and to (then) “rest-and-digest”.
