The visceral nervous system also is known as the autonomic nervous system which controls many involuntary functions of the body like arterial blood pressure regulation, pupillary and heart rate. A large amount of energy of this nerve goes to the psychological systems which require ongoing assessmentand correction. The visceral or autonomic nervous system is divided into two limbs which are, the sympathetic nervous system and the parasympathetic nervous system. They both share parts of autonomic pathways within the central and peripheral nervous system. There is only one difference between the somatic nervous system and autonomic nervous system is thedifferent pathways consistof two neurons in a series between the central neuron system and a target cell.

Functions of the visceral nervous system
There are two parts of the visceral nervous system sympathetic nervous system and parasympathetic nervous system and they both functions in opposite directions from each other. In another language sympathetic is an accelerator and parasympathetic is brake which means if they are working in the opposite direction it is great and complimentary also. The parasympathetic nervous system works when the body or organs does not need any immediate requirement of action on another hand sympathetic nervous system requires a quick response. In other terms, the sympathetic nervous system is known as fight and flight system and parasympathetic is known as rest and digest or feed and breed system.
