GENERAL HISTOLOGY

Detailed explanation-1: -Cholecystokinin (CCK) is released from mucosal endocrine cells in the proximal small intestine in response to a meal[1], and it is classically known to stimulate the gallbladder contraction.

Detailed explanation-2: -In humans, physiologic properties of CCK include the ability to stimulate gallbladder contraction, increase pancreatic enzyme secretion, delay gastric emptying, potentiate insulin secretion, and regulate food intake (table 1).

Detailed explanation-3: -Cholecystokinin (CCK) is produced by discrete endocrine cells in the proximal small intestine and is released following the ingestion of food. CCK is the primary hormone responsible for gallbladder contraction and has potent effects on pancreatic secretion, gastric emptying, and satiety.

Detailed explanation-4: -Cholecystokinin is a gut hormone released after a meal, which helps digestion and reduces appetite.

Detailed explanation-5: -Secretin mainly stimulates the secretion of pancreatic juice, which contains pancreatic enzymes and acts on the gallbladder, which can assess gallbladder function. [1] CCK increases pancreatic enzyme output and causes gallbladder contraction.
