Question

Which hormone is NOT produced by the Islets of Langerhans in the pancreas?

• A. Insulin
• B. Glucagon
• C. Somatostatin
• D. Adrenaline

Hint:

Understanding the specific hormones produced by the Islets of Langerhans is crucial for comprehending pancreatic function and disorders like diabetes mellitus.

Answer 1

The Correct Option is D

The Islets of Langerhans are clusters of endocrine cells in the pancreas responsible for producing several key hormones that regulate blood glucose levels. The primary hormones produced are:

 Insulin: Lowers blood glucose levels by facilitating cellular uptake of glucose. 

Glucagon: Raises blood glucose levels by stimulating glycogenolysis and gluconeogenesis. 

Somatostatin: Inhibits the release of both insulin and glucagon, regulating their secretion. Adrenaline, also known as epinephrine, is produced by the adrenal glands, not the Islets of Langerhans. It plays a role in the "fight or flight" response, increasing heart rate and blood glucose levels, among other functions.
Conclusion: Adrenaline is not produced by the Islets of Langerhans; it is synthesized in the adrenal medulla. % Quicktip
