Question

Duodenum has characteristic Brunner's glands which secrete two hormones called

• A. Secretin, cholecystokinin
• B. Prolactin, parathormone
• C. Estradiol, progesterone
• D. Kinase, estrogen

Answer 1

The correct option is A Secretin, cholecystokinin

Brunner's glands are compound racemose glands in the submucous layer of the duodenum. Secretin is a hormone released into the bloodstream by the duodenum (especially in response to acidity) to stimulate secretion by the liver and pancreas. Cholecystokinin is secreted by enteroendocrine cells in the duodenum, the first segment of the small intestine. Its presence causes the release of digestive enzymes and bile from the pancreas and gallbladder, respectively, and also acts as a hunger suppressant.
