Summary Introduction
Introduction:
SNS (sympathetic nervous system) represents one of the divisions of ANS (autonomic nervous system), which possesses a primary role of stimulating the body’s fight-or-flight response. However, fibers from this system innervate tissues in around every organ system, regulating at least some functions, like gut motility, urinary system output and function, and pupil diameter.
