Detailed explanation-1: -A hormone found in the pancreas, intestine, and central nervous system. It has many actions in the body, such as helping to control the secretion of water, salts, enzymes, and gastric acid during digestion.
Detailed explanation-2: -Abstract. The action of smooth muscle in the intestinal wall produces tonic contractions that maintain organ dimension against an imposed load such as a bolus of food, as well as forceful contractions that produce muscle shortening to propel the bolus along the gastrointestinal tract.
Detailed explanation-3: -Which of the following substances is released from neurons in the GI tract and produces smooth muscle relaxation? The answer is D [II C 1]. Vasoactive intestinal peptide (VIP) is a gastrointestinal (GI) neurocrine that causes relaxation of GI smooth muscle.
Detailed explanation-4: -Hormones of the Gastrointestinal tract Gastrin, secretin, cholecystokinin (CCK) and gastric inhibitory peptide (GIP) are four peptide hormones secreted by endocrine cells of the gastrointestinal tract (GIT). These hormones help in digestion by stimulating the secretion of different enzymes and gastric juices.
