The islet density routes throughout the healthy human pancreas. 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 endocrine system is made up of pituitary, pineal, thyroid, parathyroid and adrenal glands, pancreatic islet cells (also known as islets of Langerhans) and the ovaries or testicles. 1  The pituitary, pineal and parathyroid glands are neuroendocrine glands. Neuroendocrine cells in the digestive system regulate intestinal movements and the release of digestive enzymes. 2  Neuroendocrine cells in the respiratory system are believed to play a role in the developmental stages of the respiratory organs. 3  They also regulate respiratory function.
