A manual of human physiology, including histology and microscopical anatomy, with special reference to the requirements of practical medicine . the portal vein zone, whose cells under certain circumstances are particu-larly apt to undergo fatty degeneration; while there is an area lying midwaybetween the two foregoing—the hepatic artery zone—which is specially liable toamyloid or waxy degeneration.] 348 STRUCTURE OF THE LIVER. The Hepatic Cells (Fig. 141, II, a) are irregular polygonal cells of aboutth of an inch (34-45^) in diameter (Fig. 142). The arrangement of the capil-laries within a lobule determines the arrangement of the liver-cells. The liver-cells form anastomosing columns which radiate from the centre to the peripheryof each lobule (Fig. 143). [The liver-cells are usually stated to be devoid of anenvelope, although Haycraft states that they possess one. They usually containa single nucleus with one or more nucleoli, but sometimes two nuclei occur. Theprotoplasm and nucleus of each cell contains a plexus of fibrils just like otherepithelial cells. In some animals, globules of oil and pigment granules are found.
