Detailed explanation-1: -In the stomach and intestines, parasympathetic stimulation of M receptors leads to increased motility and relaxation of sphincters. Stimulation of M receptors also increases gastric secretions to aid in digestion. In the gallbladder, parasympathetic stimulation of M3 receptors stimulates contraction to release bile.
Detailed explanation-2: -The vagus nerve, also known as the vagal nerves, are the main nerves of your parasympathetic nervous system. This system controls specific body functions such as your digestion, heart rate and immune system.
Detailed explanation-3: -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.
Detailed explanation-4: -In general, sympathetic stimulation causes inhibition of gastrointestinal secretion and motor activity, and contraction of gastrointestinal sphincters and blood vessels. Conversely, parasympathetic stimuli typically stimulate these digestive activities.
