orm polygonal plates or scales, Fig. 39.—Pavement epithelhim from a serous mem-brane (peritoneum) ; magnified 410 diameters. a, cell-body ; &, nucleus ; c, nucleoli (Henle). which fit together by their edges like the tiles of a mosaic pavement. The lines oi junction of the cells may be straight, or they may be more or less jagged or sinuous. The mesodermic epithelia, such as the epithelium of serous membranes and of the vessels, belong, for the most part, to this variety, but it includes also the epithelium lining the alveoli of the lungs which is of entodermic origin ; that covering the outer surface of the membrana tympani, and that lining the mammary ducts, both of which are ectodermic. 2. Columnar. A second variety of simple epithelium is the columnar,or cylinder epithelium, in which the cells have a prismatic figure, and areset upright on the surface which they cover.
