The microscopic structure of the small intestine of the rat follows the structural plan of that in other mammals. It has four main layers: serosa, muscular layer, submucosa and mucosa. The main components of the mucosa are the crypts of Lieberkuhn embedded in lamina propria and the finger-like projections, the villi with a lamina propria core and with a single covering layer of epithelial cells. The cells of the crypts of Lieberkuhn ('crypt epithelium') and the cells covering the villi ('villus epithelium') are of common embryological origin and of similar morphological characteristics, thus together they are called the intestinal epithelium (Paneth, 1888; Heidenhain, 1888). The intestinal epithelium of the mucosa, which plays an important role in digestion, is renewed continuously from the proliferative activity of the crypt epithelial cells.
