cholecystokinin

(noun)

any of several peptide hormones that stimulate the digestion of fat and protein

Examples of cholecystokinin in the following topics:

  • The Liver and Gallbladder

    • The gallbladder has a muscular wall that contracts in response to cholecystokinin, a peptide hormone synthesized by the small intestine.
    • When food containing fat enters the digestive tract, the secretion of cholecystokinin (CCK) is stimulated, and the gallbladder releases the bile into the small intestine.

  • Hormonal Responses to Food

    • Secretin acts in tandem with another hormone called cholecystokinin (CCK).
    • Hormones, such as secretin and cholecystokinin, play important roles in digestive processes.

  • Pancreatic Juice

    • Pancreatic juice secretion is regulated by the hormones secretin and cholecystokinin.

  • Intestinal Phase

    • Chyme also stimulates duodenal enteroendocrine cells to release secretin and cholecystokinin.

  • Hormones of the Digestive System

    • Cholecystokinin (CCK) is in the duodenum and stimulates the release of digestive enzymes in the pancreas and stimulates the emptying of bile in the gall bladder.

  • Parasympathetic Responses

    • The parasympathetic nervous system uses chiefly acetylcholine (ACh) as its neurotransmitter, although peptides (such as cholecystokinin) may act on the PSNS as neurotransmitters.

  • Associated Organs

    • The exocrine function of the pancreas is controlled by the hormones gastrin, cholecystokinin, and secretin, which are hormones secreted by cells in the stomach and duodenum in response to food.
    • The muscular wall of the gallbladder contracts, releasing the bile in response to the release of cholecystokinin, a digestive hormone produced by the small intestine.

  • Digestive Processes of the Small Intestine

    • These enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in response to the presence of nutrients.

  • Organs with Secondary Endocrine Functions

    • Some of the hormones produced include gastrin, secretin, and cholecystokinin, which are secreted in the presence of food.

  • Other Hormone-Producing Structures

    • Cholecystokinin (CCK) is in the duodenum and stimulates the release of digestive enzymes in the pancreas and stimulates the emptying of bile in the gall bladder.
