Gastrointestinal physiology is the branch of human physiology that addresses the physical function of the gastrointestinal (GI) tract.The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products.
Intestinal desmosis is a medical condition implicated in gut motility disorder and chronic constipation. Desmosis can be observed as the absence of the tendinous plexus layer and connective tissue fibers.
A depiction of a slow wave, contraction and electrical threshold in relation to smooth muscle tone and resting membrane potential.. Gastric slow waves occur at around 3 cycles-per-minute in humans and exhibit significance variances in both amplitudes and propagation velocities in the stomach [8] [9] [10] due to the existence of a gradient of resting membrane potential gradient, [11 ...
Motility is the ability of an organism to move independently using metabolic energy. This biological concept encompasses movement at various levels, from whole organisms to cells and subcellular components.
Gut dysmotility is mostly caused by damage to the enteric nervous system, both structurally and functionally. [18] The enteric nervous system is highly sophisticated and can govern almost all gastrointestinal activities, including motility, independently of the central and peripheral neurological systems.
When the patient has severe, persistent signs that motility is completely disrupted, nasogastric suction and parenteral nutrition may be required until passage is restored. In such cases, continuing aggressive enteral feeding causes a risk of perforating the gut. Several options are available in the case of paralytic ileus. Most treatment is ...
Slow down in peristalsis or movement of food through the small intestine (an increase in the transit time) to increase the time available for nutrient absorption [4] Osteoporosis is a very common comorbidity in people with short bowel syndrome who are on parenteral nutrition, with an estimated prevalence of 57-67%.

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.
