In the cardiac end or fundus the glands consist of several long tubules, opening into a short, common duct, which opens by a wide mouth on the surface of the mucous membrane. Each gland consists primarily of a basement membrane lined by epithelial cells. In the duct the epithelium is of the columnar variety, resembling that covering the surface of the mucous membrane. The secretory portion of the tubule is lined by a layer of short, polyhedral, granular, and nucleated cells, which, as they border the lumen of the tubule, and thus occupy the central portion of the gland, are termed central cells. At irregular intervals, between the central cells. Fig. 13.

(See Fig. 13.) Each parietal cell is in relation with a system of fine canals, which open directly into the lumen of the gland. It is estimated that the fundus con-.
