They mostly innervate the same structures but cause opposite effects.
The autonomic nervous system has two divisions. This is why it s also called the visceral nervous system. The autonomic nervous system ans is a system of motor neurons that innervate smooth muscle cardiac muscle and glands. Autonomic nervous system ans is a functional division of the nervous system with its structural parts in both the central nervous system cns and the peripheral nervous system pns.
It is capable of acting independently of the sympathetic and parasympathetic nervous systems although it may be influenced by them. It regulates and supports many different internal processes often outside of a person s. The enteric nervous system ens or intrinsic nervous system is one of the main divisions of the autonomic nervous system ans and consists of a mesh like system of neurons that governs the function of the gastrointestinal tract.
