Where are the Langerhans islands located?

The East Frisian, the Canary Islands, the Greek Islands. Beautiful, well-known destinations. But where is it going when you go to the Langerhans Isles? Take an excursion into the interior of the human, to the pancreas.

Location of the Langerhansschen islands

The pancreas or the pancreas is a 15 - 20 cm long gland, which lies behind the stomach in the upper abdomen. Two essential functions are fulfilled by her:

  • Delivery of digestive enzymes to the intestinal lumen (exocrine function)
  • Delivery of hormones to the blood (endocrine function)

The Langerhans Islands, named after their discoverer, are distributed like an island over the entire organ and form the endocrine part of the pancreas. A healthy adult has about 1 million islet cells.

Function of the Langerhans Isles

The alpha cells of the islet organ, as the Langerhans islands are also called, produce the hormone glucagon, the antagonist to insulin that is made in beta cells. Glucagon increases blood sugar, insulin lowers it.

There are also the gamma and the delta cells, which release the growth hormone somatotropin and the growth-inhibiting hormone somatostatin to the blood.

Here ends our short trip to the Langerhansschen islands. Find out more about the pancreas and its functions in our Anatomy Lexicon, in which you can marvel at other organs in peace!
