GENERAL HISTOLOGY

Detailed explanation-1: -Pancreatic cells secrete insulin, the body’s only hormone capable of lowering plasma glucose levels. Impaired or insufficient insulin secretion results in diabetes mellitus. The cell is electrically excitable; in response to an elevation of glucose, it depolarizes and starts generating action potentials.

Detailed explanation-2: -Insulin is released from the beta cells in your pancreas in response to rising glucose in your bloodstream. After you eat a meal, any carbohydrates you’ve eaten are broken down into glucose and passed into the bloodstream. The pancreas detects this rise in blood glucose and starts to secrete insulin.
