B, urinary bladder; (?. gall-bladder; X, xiphoid cartilage, dicate course of coils of colon. The spleen was contracted. Arrows in- nearly half an inch (ca. 1 cm.) high. Sometimes it is a grooved ridge; in other cases it has the form of a rounded eminence attached by a pedicle to the wall. It consists largely of fat, but fibers from the circular muscular coat extend into it. The arrangement of the muscular coat is shoAvn in Figs. 420, 421. 1 It will be noted that the fundus gland region does not extend up to the lesser curvature; here the cardiac gland region joins the pyloric. 2 Microscopic examination shows that these regions are not sharply marked oflf from each other; instead, there are intermediate zones in which glands of both the adjacent regions are present, and also glands of intermediate histological Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Sisson, Septimus, 1865-1924.
