The division of the autonomic nervous that is short-lived and very localized is parasympathetic system.
What is nervous system?
The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The brain is what controls all the body's functions. The spinal cord runs from the brain down through the back. The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations.
The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.
