PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -The parasympathetic nervous system, also known as “rest and digest, ‘’ can be thought of as functioning in opposition to the sympathetic nervous system. Its functions include: A decrease in heart rate and contractility of cardiac muscle. Constriction of the ciliary muscle and the pupil for near vision.

Detailed explanation-2: -Your parasympathetic nervous system’s job is usually to relax or reduce your body’s activities. Because of the signals it carries, the rhyming phrases “rest and digest” or “feed and breed” are easy ways to remember what your parasympathetic nervous system does.

Detailed explanation-3: -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.

Detailed explanation-4: -The parasympathetic system is responsible for stimulation of “rest-and-digest” or “feed and breed” activities that occur when the body is at rest, especially after eating, including sexual arousal, salivation, lacrimation (tears), urination, digestion, and defecation.

Detailed explanation-5: -The parasympathetic nervous system, in contrast, exerts both excitatory and inhibitory control over gastric and intestinal tone and motility (i.e., milling, absorption, secretion, and defecation), implying a more finely tuned and complex influence over GI activity.
