GENERAL HISTOLOGY

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: -Alpha cells in the pancreatic islets secrete the hormone glucagons in response to a low concentration of glucose in the blood. Beta cells in the pancreatic islets secrete the hormone insulin in response to a high concentration of glucose in the blood.

Detailed explanation-3: -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-4: -The alpha cells of the islets of Langerhans produce an opposing hormone, glucagon, which releases glucose from the liver and fatty acids from fat tissue.

Detailed explanation-5: -This triggers your pancreas to produce glucagon. This hormone signals your liver and muscle cells to convert the stored glycogen back into glucose. These cells then release the glucose into your bloodstream so your other cells can use it for energy.
