A simplified image showing Earthworm movement via peristalsis The earthworm is a limbless annelid worm with a hydrostatic skeleton that moves by peristalsis. Its hydrostatic skeleton consists of a fluid-filled body cavity surrounded by an extensible body wall.
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. [1]
A prokinetic agent (also prokineticin, gastroprokinetic agent, gastrokinetic agent or propulsive) is a type of drug which enhances gastrointestinal motility by increasing the frequency or strength of contractions, but without disrupting their rhythm. [1]
The peristalsis and segmentation, detailed below and pendular movement are famous examples of distinct patterns of GI contraction. [5] Occurring between meals, the migrating motor complex is a series of peristaltic wave cycles in distinct phases starting with relaxation, followed by an increasing level of activity to a peak level of peristaltic ...
Smooth muscle within the GI tract causes the involuntary peristaltic motion that moves consumed food down the esophagus and towards the rectum. [1] The smooth muscle throughout most of the GI tract is divided into two layers: an outer longitudinal layer and an inner circular layer. [1] Both layers of muscle are located within the muscularis ...
Laxatives, purgatives, or aperients are substances that loosen stools [1] and increase bowel movements. ... and acetic acids; and increasing colonic peristalsis.
Minnesota Wild forward Ryan Hartman on Sunday has been offered an in-person hearing with the NHL Department of Player Safety, one day after he received a match penalty for roughing Ottawa Senators ...
These motor complexes trigger peristaltic waves, which facilitate transportation of indigestible substances such as bone, fiber, and foreign bodies from the stomach, through the small intestine, past the ileocecal sphincter, and into the colon. MMC activity varies widely across individuals and within an individual when measured on different days.
