The Autonomic Nervous System
- One of the two main divisions of the autonomic nervous system, the sympathetic nervous system's primary process is to stimulate the body's fight-or-flight response.
- The parasympathetic nervous system's primary process is responsible for stimulation of 'rest-and-digest' or 'feed and breed' activities that occur when the body is at rest.
