Pancreas (SFLT)

Pancreas HE - clear magnification[edit | edit source]

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[edit | edit source]

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.

Description:Exocrine acini with intralobular outlet.

Pancreas HE - detail of the islet of Langerhans[edit | edit source]

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.

Description: 1 - Islet of Langerhans (endocrine pancreas), 2 - serous acini (exocrine pancreas), 3 - interlobular duct, 4 - multi-row cylindrical epithelium of the interlobular duct, the cells of which produce mucus (PAS+), 5 - fibrous septum.
