What stimulates gastric emptying?
Cholecystokinin inhibits gastric emptying by acting on both proximal stomach and pylorus. Cholecystokinin is a potent inhibitor of gastric emptying. It is known to both relax the proximal stomach and contract the pyloric sphincter, and either one or both of these actions could mediate inhibition of gastric emptying.
What hormones stimulate gastric emptying?
|Gastrin||Stimulates gastric acid secretion and proliferation of gastric epithelium|
|Cholecystokinin||Stimulates secretion of pancreatic enzymes, and contraction and emptying of the gall bladder|
