The posterior border presents a deep notch (Incisura pancreatis) where the root of the great m(>sentery is in contact with the glantl. To the right the portal vein lies in the notch, and passes through the gland very obliciuely; there is a thin. Fig. 371.—Pancreas of Horse with Chief Relations; Ventral View. The pancreatic duct and its two chief radicles are indicated by dotted lines, since they are in the substance of the gland. bridge of gland tissue dorsal to the vein, thus forming the portal ring (Annulus portae). The anterior or duodenal angle (Angulus cranialis)' is the most ventral part of the gland; it is attached to the concavity of the second curve of the duodenum and the adjacent part of the right lobe of the liver. The ducts leave at this ex- tremity. The left or splenic angle (Angulus sinister)- fits into the space between the saccus ceecus of the stomach in front, the left kidney behind, the base of the spleen dorsally, and the termination of the great colon ventrally. The right angle (Angulus dexter) is rounded, and lies on the ventral surface of the right kidney and adrenal body.
