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.

cholecystokinin

/cho·le·cys·to·ki·nin/ (CCK) (-ki´nin) a polypeptide hormone secreted in the small intestine that stimulates gallbladder contraction and secretion of pancreatic enzymes.

cholecystokinin

(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.

cholecystokinin

[-kī′nin]
Etymology: Gk, chole + kystis, bag, kinein, to move
a hormone produced by the mucosa of the upper intestine that stimulates contraction of the gallbladder and secretion of pancreatic enzymes.

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.

cholecystokinin (kōˈ·li·sis·tō·kīˑ·nin),

n a substance produced in the body that acts as a neurotransmitter, opiate antagonist, and hormonal peptide and that is involved in digestive processes and the experience of satiety.

cholecystokinin

a gastrointestinal hormone liberated from the intestinal mucosa in response to arrival of the products of digestion from the stomach. It stimulates secretion of pancreatic enzymes and gallbladder contraction. Abbreviated CCK, CCK-PZ. Called also cholecystokinin-pancreozymin, pancreozymin.
