. The anatomy of the domestic animals. Veterinary anatomy. THE STOMACH 499 The serous coat is almost complete. Along the curvatures it leaves the stom- ach to form the omenta. The longitudinal muscular fibers are chiefly along the curvatures and on the pyloric part; they are continuous with the external layer of the CESophagus. The oblique fibers are arranged in two layers: the external layer is largely a continuation of the longitudinal fibers of the oesophagus to the body and fundus. The circular layer covers the whole stomach except the fundus, and forms a pyloric sphincter and an antral sphincter. The internal oblique layer is arranged as in the horse, and forms a similar loop-like, cardiac sphincter. Three regions of the mucous membrane exist. Cardiac glands are found in a very narrow pale zone around the cardiac opening, and also scattered along the lesser curva-.

The fundus gland region has a thick, reddish-bro^vn mucous membrane, which lines about two-thirds of the organ. The pyloric mucous membrane is thimicr ami pale; in the dead subject it is often stained by regurgitated bile. The greater omentiun is very extensive, and in well-nourished subjects it con- tains much fat arranged in interlacing strands. Viewed ventrally it covers the entire intestinal mass, extending from the greater curvature of the stomach to the pelvic inlet. It is attached to the greater curvature of the stomach, the left part of the colon, the left liranch of the pancreas, and the hilus of the spleen. The lesser omentum extends from the lesser curvature of the stomach to the portal fissure; to reach the latter it passes in great part between the papillary and left lateral lobes of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - co
