Detailed explanation-1: -Explanation: The cerebellum, which is located behind and below the cerebrum, controls and coordinates muscle movement. The pre-nursing class is learning about the nervous system in their anatomy class.

Detailed explanation-2: -The parasympathetic division of the autonomic nervous system works to conserve body energy and is partly responsible for slowing heart rate, digesting food, and eliminating body wastes.

Detailed explanation-3: -The parasympathetic nervous system originates from medial medullary sites (nucleus ambiguous, nucleus tractus solitarius, and dorsal motor nucleus) and is modulated by the hypothalamus. The preganglionic neurons of the PNS come from brainstem nuclei and the sacral spinal cord (specifically S2-S4).

Detailed explanation-4: -Digestion: The PSNS stimulates the release of saliva to promote digestion. It also enacts peristalsis, or the movement of the stomach and intestines, to digest food as well as release bile for the body to digest fats.

Detailed explanation-5: -Your parasympathetic nervous system is a network of nerves that relaxes your body after periods of stress or danger. It also helps run life-sustaining processes, like digestion, during times when you feel safe and relaxed.
