What is All of the following increase small intestinal motility except and explain in detail?
Secretin inhibits small intestinal motility. Factors that increase the peristaltic activity of small intestine Hormonal- Gastrin, CCK, insulin, motilin and serotonin Neural - Duodenal distension by chyme, gastroenteric reflex, gastroileal reflexes, parasympathetic (ACh) stimulation. Factors that decrease the peristaltic activity of small intestin: Hormone- Secretin and glucagon Neural- Sympathetic stimulation Gastroileal reflex- On reaching the ileocecal valve, the chyme is sometimes blocked for several hours until the person eats another meal. At that time, a gastroileal reflex intensifies peristalsis in the ileum and forces the remaining chyme through the ileocecal valve into the cecum of the large intestine.
