about to the middle of the stomach. The fundus gland region is readily distin- 
guished by its thickness (ca. 3 mm.) and its brownish-red, mottled appearance.’ 
The fourth or pyloric region is pale, thinner than the preceding, and presents a 
number of irregular folds.2 At the pylorus a remarkable prominence (Torus pylo- 
ricus) projects from the wall of the lesser curvature and diminishes considerably 
the size of the orifice. It is about an inch and a half (ca. 3 to 4 em.) long and

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 shown in Figs. 420, 421. 
lit will be noted that the fundus gland region does not extend up to the lesser curvature; 
here the cardiac gland region joins the pyloric. 
* Microscopic examination shows that these regions are not sharply marked off from each 
other; instead, there are intermediate zones in which glands of both the adjacent regions are 
present, and aiso glands of intermediate histological character.
