Question

Explain how hormones, nervous system stimulation, and the volume, chemical composition, and osmolarity of the chyme affect motility in both the stomach and the duodenum

Answer 1

Genetics are thought to play a role in certain gastric motility disorders, such as hirschusprung's disease , intestinal pseudo- obstruction and GERD.

Hormones which controls the different digestive enzymes that secreted in stomach and the intestine during the process of digestion and absorption. Stomach secret the acid in response to food intake which is stopped by the somatostain. This stimulates the gastric mobility.

Duodenum mobility is effect by the input form the central nervous system which reduce the propagation velocity and increase contractile amplitudes. (CRF) Corticopin -releasing factor is physiologic mediator of stress effects on the gut. An antroduodenal mobility is diagnosis problem in the muscles of stomach and small intestine are working.
