PATHOLOGY

Detailed explanation-1: -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-2: -Doctors often call the parasympathetic nervous system the “rest and digest” side, while the sympathetic is the “fight or flight.”

Detailed explanation-3: -Muscarinic receptors are G-coupled protein receptors involved in the parasympathetic nervous system. The only exception to these receptors is the sweat glands, which possess muscarinic receptors but are part of the sympathetic nervous system.
