MICROANATOMY

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 allows the cells in the muscles, fat and liver to absorb glucose that is in the blood. The glucose serves as energy to these cells, or it can be converted into fat when needed. Insulin also affects other metabolic processes, such as the breakdown of fat or protein.

Detailed explanation-3: -Insulin is essential in maintaining normal blood glucose levels and is produced and secreted by the beta cells of pancreas in response to increased blood glucose levels.
