MICROANATOMY

Detailed explanation-1: -Glucagon is a peptide hormone secreted from the alpha cells of the pancreatic islets of Langerhans. Hypoglycemia is physiologically the most potent secretory stimulus and the best known action of glucagon is to stimulate glucose production in the liver and thereby to maintain adequate plasma glucose concentrations.

Detailed explanation-2: -Glucagon is a hormone that is involved in controlling blood sugar (glucose) levels. It is produced by the alpha cells, found in the islets of Langerhans, in the pancreas, from where it is released into the bloodstream.

Detailed explanation-3: -The islets of Langerhans (white) contain alpha-cells that produce glucagon and beta-cells that are responsible for the production of insulin.

Detailed explanation-4: -Alpha cells, by contrast, produce glucagon, a hormone that has blood glucose-increasing effects.

Detailed explanation-5: -Glucagon is a hormone that triggers liver glycogen to convert back into glucose and to enter your bloodstream so that your body can use it for energy.
