The goal of GIT regulation is to ensure proper functioning. The neuronal and hormonal systems work together to regulate secretomotor function, motility, and cell growth in the GI tract. Key neurotransmitters and hormones, such as acetylcholine, gastrin, and cholecystokinin, are involved in signaling between nerve endings and target organs to modify GI secretion and movement in response to food intake. Several reflexes also help regulate the GI system, including the peristaltic, vagovagal, and enterogastric reflexes, which impact motility, secretion, and the release of gastrin.
