Endocrine pancrease
What are the 4 hormone prodlucing cells of the endocrine pancreas and what do they produce?
- Alpha- glucagon
- Beta- insulin
- Delta- Somatostatin
- F cell- Pancreatic polypeptide
What is the most common cell type of the endocrine pancreas
Beta cells
A polypeptide hormone produced by beta cells in response to hyperglycemia
insulin
insulin consists of 2 chains, alpha and beta, conected by:
2 disulfide bridges
T/F porcine and canine insulin are exactly the same
T
T/F Bovine insulin differs from a cat by 10 AA
F 1 AA
Stimuli for Insulin secretion
- GI hormones (gastrin, secretin, GIP
- Acetylcholine
- Glucose (omnivors)
- AA (Carnivors)
- Fatty acids
inhibitors for insulin secretion
- Somatostatin
- Epinephrine
- Norepinephrine
4 Glucagon
