During the cephalic phase of gastric secretion?
the stomach responds to distention production of gastric juice slows down. secretin inhibits parietal and chief cells
the intestinal reflex inhibits gastric emptying
there is an increased flow of action potentials along the vagus nerve to the stomach .

there is an increased flow of action potentials along the vagus nerve to the stomach. The cephalic phase is the preparatory phase of gastric secretion that begins before food enters the stomach. It is triggered by the sight, smell, taste, or anticipation of food. In this phase, the brain sends signals through the vagus nerve to stimulate the secretion of gastrin, a hormone that triggers the release of gastric juice. The increased flow of action potentials along the vagus nerve results in the release of acetylcholine, which stimulates parietal and chief cells to produce gastric juice.
