Study Notes
Islets of Langerhans Overview
- The Islets of Langerhans are clusters of cells in the pancreas that play a crucial role in endocrine function, not composed of adipose tissue.
- Their primary function is to regulate blood glucose levels in the body, maintaining homeostasis.
Hormones Produced
- Insulin is a key hormone produced by the beta cells in the Islets of Langerhans, essential for lowering blood sugar levels.
- Glucagon, produced by alpha cells, acts to increase blood sugar levels when they drop too low.
Cell Types and Functions
- Beta cells: Produce insulin, important for glucose uptake by cells.
- Alpha cells: Produce glucagon, which stimulates the liver to release glucose into the bloodstream.
- Delta cells: Produce somatostatin, which regulates the secretion of both insulin and glucagon.
- PP cells (Pancreatic Polypeptide cells): Produce pancreatic polypeptide, which influences the digestion and absorption of nutrients.
