CCK A hormone produced principally by the small intestine in response to the presence of fats, causing contraction of the gallbladder, release of bile, and secretion of pancreatic digestive enzymes. Also called pancreozymin.cholecystokinin (ˌkɒlɪˌsɪstəˈkaɪnɪn) n (Biochemistry) a hormone secreted by duodenal cells that stimulates the contraction of the gall bladder and secretion of pancreatic enzymes. Also called: pancreozymin cho•le•cys•to•ki•nin (ˌkoʊ ləˌsɪs təˈkaɪ nɪn, ˌkɒl ə-)
n. a hormone secreted by the upper intestine that stimulates contraction of the gallbladder and increases secretion of pancreatic juice. Abbr.: CCK [1925–30] cholecystokininA hormone that causes the gallbladder to contract and so release bile into the duodenum.Thesaurus| Noun | 1. | cholecystokinin - a gastrointestinal hormone that stimulates the secretion of pancreatic enzymes and the contraction and emptying of the gall bladder; its release is stimulated by the presence of fatty acids and amino acids in the small intestinegastrointestinal hormone, GI hormones - hormones that affect gastrointestinal functioning |

cholecystokinin[‚kō·lə‚sis·tə′kī·nən] (biochemistry) A hormone produced by the mucosa of the upper intestine which stimulates contraction of the gallbladder. cholecystokininenUK
cholecystokinin [ko″le-sis″to-ki´nin] a polypeptide hormone secreted in the small intestine, which stimulates gallbladder contraction and secretion of pancreatic enzymes.cho·le·cys·to·ki·nin (CCK), (kō'lē-sis-tō-kī'nin), [MIM*118440] A polypeptide hormone (the human peptide has 33 residues) liberated by the upper intestinal mucosa on contact with gastric contents; stimulates contraction of the gallbladder and secretion of pancreatic juice. Synonym(s): CCK-pancreozymin, pancreozymincholecystokinin (kō′lĭ-sĭs′tə-kī′nĭn)n. Abbr. CCK A hormone produced principally by the small intestine in response to the presence of fats, causing contraction of the gallbladder, release of bile, and secretion of pancreatic digestive enzymes. Also called pancreozymin.cho·le·cys·to·ki·nin (CCK) (kō'lĕ-sis'tō-kī'nin) A polypeptide hormone liberated by the upper intestinal mucosa on contact with gastric contents; stimulates contraction of the gallbladder and secretion of pancreatic juice. cholecystokinin A HORMONE released into the blood from the lining of the duodenum when fat and acid are present. It causes the gallbladder to contract and the sphincter of Oddi to relax, so sending bile into the duodenum to emulsify the fat, and stimulates the pancreas to secrete fat- and protein-splitting enzymes. The hormone also inhibits the motility of the stomach and the secretion of gastric acid.cholecystokinin (CCK) (formerly pancreozymin) ) a single hormone secreted by the wall of the duodenum in mammals when food enters the small intestine. CCK causes contraction of the gallbladder muscle, resulting in bile being pumped into the duodenum via the bile duct, and stimulates the pancreas to secrete pancreatic juice containing large quantities of digestive enzymes, which enter the duodenum via the lower part of the bile duct. CCK causes VASODILATION of the intestinal blood vessels.AcronymsSeeCCKcholecystokininenUK
