What are the eyelets of langerhans?

The islets of Langerhans are clusters of endocrine cells located in the pancreas. They play a crucial role in regulating blood sugar levels by producing hormones, primarily insulin and glucagon. Insulin lowers blood glucose levels, while glucagon raises them, together maintaining glucose homeostasis in the body. These islets contain different cell types, including alpha, beta, and delta cells, each responsible for producing specific hormones.
