Islet of Langerhans
The islets of Langerhans are the areas of the pancreas containing the endocrine cells responsible for producing the hormones that are secreted by the pancreas. The areas are named after Paul Langerhans, a German anatomist, in 1869.
There are 5 cell types in the islets of Langerhans responsible for producing different hormones:
- Alpha cells: produce glucagon
- Beta cells: produce insulin and amylin
- Delta cells: produce somatostatin
- PP cells: produce pancreatic polypeptide
- Epsilon cells: produce ghrelin
