WebPancreas is a compound gland. In addition to secreting digestive enzymes, the pancreas is an important endocrine gland. Its hormones, insulin and glucagon, are secreted by cells, that occur in little clusters, the islets of Langerhans, throughout the pancreas. About 1 million islets are present in the human pancreas.
Webislets of Langerhans: ( lahng'ĕr-hahnz ), cellular masses consisting of several to several hundred cells lying in the interstitial tissue of the pancreas; they are composed of five different cell types that make up the endocrine portion of the pancreas and are the sources of insulin, glucagon, somatostatin, pancreatic polypeptide, and gastrin. ... WebIslets of Langerhans are distributed throughout the adult organ and are supported by a mass of branching exocrine tissue. Islets vary considerable in size, but a typical islet is around 50–200 μM in diameter. In mouse islets, β cells are found to be clustered together in the core of each islet, surrounded by peripheral hormone secreting ...
