Question

Hormone involved in discharge of pancreatic secretions is

• A. Gastrin
• B. Cholecystokinin
• C. Secretin
• D. Both B and C

Answer 1

The correct option is D Both B and C

A. Gastrin is secreted in stomach by the parietal cells and stimulates the secretion of gastric juices from the gastric glands.

B. Cholecystokinin is secreted from the duodenum and causes contraction of gall bladder and secretion of pancreatic juice into duodenum.

C. Secretin is secreted in duodenum and stimulates the secretion of pancreatic juice but inhibits the secretion of gastric juices.

Hence, both cholecystokinin and secretin are involved in discharge of pancreatic secretions. So both options B and C are correct.

So, the correct answer is 'Both B and C'.
