Answer 2

Answer:

The parasympathetic nervous system (PSNS) is a division of the autonomic nervous system (ANS) that controls the activity of the smooth and cardiac muscles and glands. It works in synergy with the sympathetic nervous system (SNS), which complements the PSNS activity. The parasympathetic nervous system is also called the craniosacral division of the ANS, as its central nervous system components are located within the brain and the sacral portion of the spinal cord.

The functions of the PNS are commonly described as the “rest and digest” response, since it is involved in slowing down the heart rate, relaxing the sphincter muscles in the gastrointestinal and urinary tracts and increasing intestinal and gland activity. The final result is conserving energy and regulating basic bodily functions such as digestion and urination. It is contrasted to the sympathetic nervous system, which is described as the “fight and flight” response that occurs in stressful situations and has mainly opposite functions.
