Summary Introduction
To review:
The division of ANS (autonomic nervous system) that is activated upon actions and induces the pumping of heart and sweating.
Introduction:
The autonomic nervous system refers to a system of motor neurons that innervates the cardiac muscle, glands, and smooth muscles of the body. This system is involved in the regulation of various visceral functions, for instance, urination, blood pressure, heart rate, and digestion. The autonomic nervous system is classified into sympathetic and parasympathetic divisions.
