Detailed explanation-1: -Glucagon retards gastric emptying of liquids and inhibits motility throughout the gastrointestinal tract [63].
Detailed explanation-2: -Discharge of vagal efferent neurons is stimulated by the action of CCK on CCK-1 receptors and increase intracellular calcium. They find these neurons in both the stomach and small intestines, and CCK initially activates the afferent fibers in the small intestine via a paracrine mechanism.
Detailed explanation-3: -Blocking CCK-A receptors accelerates gastric emptying of liquid meals and abolishes the gastrocolonic reflex. Therefore, CCK may play a role as a common regulator of postprandial gallbladder contraction and pancreatic enzyme secretion as well as of gastric emptying rates under certain conditions.
