Autonomic Nervous System

Image Description:

An image showing the Autonomic Nervous System.

Sympathetic and parasympathetic nerves nerves the same organs, usually one slowing them down and the other accelerating.

The sympathetic nervous system has a "pearl neck" of ganglia on both sides of the spine. (Red) Sympathetic nerves pass along the thoracic and lumbar nerves.

(Blue) Parasympathetic nerve cells travel with the cerebral and sacral nerves.

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.
