Basal electrical rhythm is a slow wave of electrical activity that can initiate a contraction. Catastalsis is a related intestinal muscle process. [8] Ileus is a disruption of the normal propulsive ability of the gastrointestinal tract caused by the failure of peristalsis. Retroperistalsis, the reverse of peristalsis
The gastrocolic reflex or gastrocolic response is a physiological reflex that controls the motility, or peristalsis, of the gastrointestinal tract following a meal. It involves an increase in motility of the colon consisting primarily of giant migrating contractions, in response to stretch in the stomach following ingestion and byproducts of digestion entering the small intestine.

Distension of the stomach increases motility of the stomach. [2] Distension of the duodenum inhibits stomach motility in order to prevent the over filling of the duodenum. [2] Presence of fat, low pH, and hypertonic solutions cause a decrease in motility of the stomach. [2] Sympathetic nervous system innervation inhibits gastric motility. [2]
Gastroparesis (gastro- from Ancient Greek γαστήρ – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period of time.
A slow-wave potential is a rhythmic electrophysiological event in the gastrointestinal tract. The normal conduction of slow waves is one of the key regulators of gastrointestinal motility. [ 1 ] Slow waves are generated and propagated by a class of pacemaker cells called the interstitial cells of Cajal , which also act as intermediates between ...
These slow wave potentials must reach a threshold level for the action potential to occur, whereupon Ca 2+ channels on the smooth muscle open and an action potential occurs. As the contraction is graded based upon how much Ca 2+ enters the cell, the longer the duration of slow wave, the more action potentials occur. This, in turn, results in ...
"Capsaicin can actually trigger some people to have diarrhea (because) in the intestines, it can speed up motility," says de Latour. As capsaicin moves through the rectum and anus, it may cause a ...
The nervous system, and endocrine system collaborate in the digestive system to control gastric secretions, and motility associated with the movement of food throughout the gastrointestinal tract, including peristalsis, and segmentation contractions.
