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: -When blood sugar levels are too low, the pancreas releases glucagon into the bloodstream. This hormone does the opposite of what insulin does: It causes the liver cells to release stored sugar. It also makes sure that proteins in the liver are turned into sugar that can then be used for energy.

Detailed explanation-3: -The secretion of glucagon by pancreatic -cells plays a critical role in the regulation of glycaemia. This hormone counteracts hypoglycaemia and opposes insulin actions by stimulating hepatic glucose synthesis and mobilization, thereby increasing blood glucose concentrations.

Detailed explanation-4: -Glucagon is a hormone your pancreas makes that triggers glycogen to convert back into glucose and to enter your bloodstream so your body can use it for energy. Glucagon and insulin are the primary natural hormones that regulate your body’s blood glucose levels.
