This Concept Map, created with IHMC CmapTools, has information related to: Gut Motility, Small Intestine Churning, Stomach Peristalsis begins in the middle of the body of the stomach. Pushes food towards the pyloric antrum. Small amount of chyme is moved into the duodenum before the pyloric sphincter closes. Remainder of bolus is moved back into the stomach to be broken down further (retropulsion), Stomach Distension triggers vagovagal response to induce relaxation of the orad region, accomodating more food without increase in intragastric pressure (mediated by VIP), Gut Motility Governed by the Enteric Nervous System, Migrating myoelectric complex* Travels through Stomach, Governed by the Enteric Nervous System Maximum pace of action potentials determined by interstitial cells of Cajal*, Gut Motility Stomach, Modified by autonomic nervous system Parasympathetic stimulation increases gut function and motility, Large Intestine Rectum & Anus, Large Intestine Churning, Governed by the Enteric Nervous System Modified by autonomic nervous system, Gut Motility Drugs that modify kinetics, Large Intestine Mass Peristalsis, Maximum pace of action potentials determined by interstitial cells of Cajal* Highest rate is the duodenum: 12 slow waves/min, Modified by autonomic nervous system Sympathetic stimulation decreases gut function and motility, Rectum & Anus Rectosphincteric Reflex*, Churning Same mechanism as small intestine Churning, Small Intestine Propulsion, Migrating myoelectric complex* Travels through Small Intestine, Stomach Small Intestine
