GENERAL HISTOLOGY

Detailed explanation-1: -Glucagon and insulin are both important hormones that play essential roles in regulating your blood glucose (sugar). Both hormones come from your pancreas-alpha cells in your pancreas make and release glucagon, and beta cells in your pancreas make and release insulin.

Detailed explanation-2: -Glucagon is a peptide hormone secreted from the alpha cells of the pancreatic islets of Langerhans.

Detailed explanation-3: -Insulin is released by the ‘beta cells’ in the islets of Langerhans in response to food. Its role is to lower glucose levels in the bloodstream and promote the storage of glucose in fat, muscle, liver and other body tissues. ‘Alpha cells’ in the islets of Langerhans produce another important hormone, glucagon.

Detailed explanation-4: -There are specialised areas within the pancreas called islets of Langerhans (the term insulin comes from the Latin insula that means island). The islets of Langerhans are made up of different type of cells that make hormones, the commonest ones are the beta cells, which produce insulin.

Detailed explanation-5: -Pancreas. The pancreas is located across the back of the abdomen, behind the stomach. The pancreas plays a role in digestion, as well as hormone production. Hormones produced by the pancreas include insulin and glucagon, which regulate levels of blood sugar.
