Question

Name the hormones secreted by these cells of the pancreas :

1. Beta cells
2. Alpha cells
3. Delta cells

Answer 1

Islets of Langerhans:

1. The islets of Langerhans are the group of cells that make up the endocrine part of the pancreas gland.
2. There are 3 types of cells, each performing a specific function.
3. Beta cells - They secrete insulin which helps in bringing down the blood sugar level by depositing extra glucose in the liver and muscle cells in the form of glycogen.
4. Alpha cells - They secrete glucagon which increases the blood sugar level by converting stored glycogen in the liver to glucose.
5. Delta cells - They secrete somatostatin also called GHIH (growth hormone inhibiting hormone) which is an inhibitory hormone that inhibits the secretion of insulin and glucagon.
