Question

Which of the following is NOT a hormone secreted by islets of Langerhans?
1. Soatostatin
2. Glucocorticoids
3. Glucagon
4. Insulin

Answer 1

Correct Answer - Option 2 : Glucocorticoids

The correct answer is Glucocorticoids.

• Glucocorticoids are secreted by adrenal glands. In response to signals from a brain region called the hypothalamus, the adrenal glands secrete glucocorticoids, hormones that produce a response to stress. 
• The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain it's endocrine (hormone-producing) cells, discovered in 1869 by German pathological anatomist Paul Langerhans. 
• There are five types of cells in the islets of Langerhans:
  • Beta cells secrete insulin
  • Alpha cells secrete glucagon
  • PP cells (also called F cells) secrete pancreatic polypeptide
  • Delta cells secrete somatostatin
  • Epsilon cells secrete ghrelin.
