MICROANATOMY

Detailed explanation-1: -The endocrine pancreas consists of the islets of Langerhans. There are approximately one million islets that weigh about 1 gram (about 0.04 ounce) in total and are scattered throughout the pancreas. The cells that make up the islets arise from both endodermal and neuroectodermal precursor cells.

Detailed explanation-2: -What are islets? Pancreatic islets, also called islets of Langerhans, are groups of cells in your pancreas. The pancreas is an organ that makes hormones to help your body break down and use food. Islets contain several types of cells, including beta cells that make the hormone insulin.

Detailed explanation-3: -Islets typically consist of four types of secretory endocrine cells, namely, the insulin-containing cells, the glucagon-containing cells, the somatostatin-containing cells, and the pancreatic polypeptide-producing (PP) cells.
