Flashcards

Islets of Langerhans function?

Regulate blood sugar levels by secreting hormones like insulin and glucagon.

Islets of Langerhans: Adipose tissue?

False. They are clusters of endocrine cells, not primarily adipose tissue.

Hormone of Islets of Langerhans?

Insulin, which lowers blood glucose levels.

Islets regulate what levels?

Blood sugar. The islets help maintain glucose homeostasis.

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.
