Sympathetic nervous system

Explanation:

This entire physiological process in the face of any stimulus and situation of high emotional connotation, such as nervousness or hyperactivity, is organized by an injury to the sympathetic nervous system.

The sympathetic nervous system is one of the branches of the autonomic nervous system. We must remember first of all that we are dealing with a type of structure that is responsible for a large number of involuntary functions. That is, tasks such as heart rate control, digestion, sweating, etc. These dimensions are regulated by both the sympathetic and parasympathetic or enteric nervous systems. The sympathetic nervous system also regulates reactions such as nervousness, bouts, feelings of escape and hyperactivity.
