Pancreas (SFLT)

Pancreas HE - clear magnification


Description: The pancreas is a gland composed of an exocrine, acinous serous gland (2) and endocrine islets of Langerhans (1). Duct system of exocrine gland begins inside acinus as centroacinous cells, continues as inserted ducts. Intralobular, interlobular (in ligament sept - 3), lobar and main exits continue. Except for the inserted ducts, which are lined by a single-layered squamous epithelium, all other ducts are made up of columnar epithelium, the cells of which can produce mucus; 4 - fat cells.

Pancreas HE - detail of serous acini


Description: In contrast to the parotid gland, we do not find annealed ducts in the pancreas. Exocrine tissue is made up of serous acini. Serous cells produce digestive enzymes (proteins) and their nuclei are round. Rough endoplasmic reticulumis very abundant in the basal part of the cell.

Pancreas HE - detail of the islet of Langerhans


Description: The endocrine cells of the islet of Langerhans are brighter than the exocrine cells. They are arranged in beams. The beam-like structure allows the cells to come into contact with the blood vessels, into which they deliver their secretion (hormone). Individual types of endocrine cells can only be recognized by immunohistochemical detection of the hormone or in an electron microscope.
