lThe parasympathetic nervous system is one of three divisions of the autonomic nervous system.
Sometimes called the rest and digest system, the parasympathetic system conserves energy as it slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract.
The sympathetic nervous system (SNS) is part of the autonomic nervous system (ANS), which also includes the parasympathetic nervous system (PNS).
The sympathetic nervous system activates what is often termed the fight or flight response.
Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons.
