[Structure of the epithelium in the large milk ducts and milk sinuses of the bovine udder].
The two-layered epithelium of the large milk ducts and the milk sinus of the bovine udder were studied by light and electron microscopy. Whereas the cells of the basal cell layer are poor in cell organelles, the cells of the apical layer shows many cell organelles and microvilli at the surface. This hints at processes of reabsorption through the apical cell layer. Together with the fast junctional complex between the cells, this confirmes the function of the epithelium as a barrier within the local defense system of the bovine udder.
