EELATIONS AND CONNEXIONS OF THE STOMACH. 1169 the incisura angularis on the lesser curvature, and to the notch on the greater curvature already described. It forms a rounded chamber, capable of great disten- sion, but when the stomach is empty it contracts to a narrow tube-like structure. As the stomach is seldom completely empty, the body usually tapers from the fundus to the proximal end of the pyloric portion. Pars Pylorica.—The pyloric portion of the stomach extends from the incisura angularis in the lesser curvature, and a variable and inconstant notch on the greater curvature, as far as to the pyloric orifice. It differs from the body of the stomach in being more tubular in shape, and possessing thicker walls. It has been divided anatomically into two portions, the pyloric canal and the antrum pyloricum respectively. The pyloric canal is a short more or less tubular portion rather more than an inch in length, extending from the sulcus intermedins on the greater curva- ture to the pyloric constriction. The proximal portion, called the pyloric antrum, Incisura ansularis Fold of stomach wall Pylorus ^Vesica fellea Omentum maju; Ductus hepaticus and arteiia cystica.

It is not clearly demarcated from the body of the stomach by any constant line of division on the greater curvature. On the lesser curvature it extends from the incisura angularis to the pyloric canal, and it is occasionally pouched outwards on the side of the greater curvature so as to form a chamber or pouch, the " camera princeps " of His.
