Hormones - Pancreatic Islets Flashcards
What are the hormones of the pancreatic islets (4)
- Glucagon
- Insulin
- Somatostatin
- Pancreatic polypeptide
What is the source of glucagon?
Alpha cells
What is the source of insulin?
Beta cells
What is the source of Somatostatin?
Delta cells
What is the action of glucagon
Promote glucose movement from storage to blood
Increase blood fatty acids
What is the action of insulin
Promote glucose from blood to cells
Decrease amino acids and fatty acids
What is the action of somatostatin
Regulation of secretion of other pancreatic hormones
