Detailed explanation-1: -The GI hormones that primarily stimulate motor activity are gastrin, CCK, and motilin, while the peptides that inhibit motor activity are secretin, VIP, glucagon, and enteroglucagon.
Detailed explanation-2: -As two of the first gastrointestinal peptides discovered, gastrin and CCK are known to play important roles in digestive processes including gastric acid secretion, pancreatic enzyme release, gallbladder emptying, gut motility, and energy homeostasis (2–4).
Detailed explanation-3: -Under normal physiologic conditions, secretin inhibits gastrin release; however, in gastrinoma pathologies, the administration of secretin will cause an overall increase in gastrin release. This idea is the basis for the secretin stimulation test, which is used to determine the presence of gastrin-producing tumors.
