The pancreatic islets or islets of Langerhans are the regions of the pancreas that contain its endocrine (i.e., hormone-producing) cells. Discovered in 1869 by German pathological anatomist Paul Langerhans, the pancreatic islets constitute approximately 1-2% of the pancreas's mass and receive 10-15% of its blood flow.here are about one million islets distributed throughout the pancreas of a healthy adult human, :914 each of which measures about 0.2 mm in diameter.
Delta cells make up 5% of the pancreatic cells in the Islets of Langerhans and are located variably in the area and release somatostatin, produce somatostatin, which acts within the islets of Langerhan to inhibit the production of both glucagon and insulin, slows GI motility, allowing more time for food to be absorbed.istology of Pancreatic Islets of Langerhans. 1-two million Islets in human 2- in the islets the cells are arranged in irregular chains and cords separated by a rich blood supply; 3- cells in islets: alpha cells (70%) secrete insulin and beta cells(20%) secrete glucagon.
