PANCKEAS. 1207 a rather sinuous or zigzag course (Fig. 948) through the axis of the gland, at first running transversely to the right, until the neck is reached, then bending down- wards towards the head. Here it, approaches the descending part of the duodenum, and meeting the bile-duct, the two pierce the medial wall of the gut obliquely (for | to | of an inch, 12 to 18 mm.), and open, by a common orifice on the duodenal papilla, about 3£ or 4 inches (8'7 to 10 cm.) beyond the pylorus (see p. 1203). In its course through the gland the duct receives numerous branches, which join it, as a rule, nearly at a right angle. These ducts, as well as the main duct itself, are easily recognised by the whiteness of their walls, which contrasts with the darker colour of the gland tissue. The main duct receives branches from all portions of the pancreas, and towards its termination attains a considerable size (namely, J^-th to £th of an inch—2-5 to 4 mm.—when flattened out, or somewhat larger than a crow quill). Superior part of duodenum Accessory pancreatic duct Pancreatic duct. Bile-duct Superior mesenteric artery Superior mesenteric vein Head of pancreas Branch of accessory duct Fig. 948.—Posterior Aspect op the Pancreas and Duodenum, with the pancreatic duct exposed. The superior mesenteric vessels are also shown in section, passing forwards, surrounded by the recurved portion of the head of the pancreas. The pancreatic accessory duct ( duct of Santorini) is a small and variably developed duct (Fig. 948) which opens into the duodenum about f of an inch above and somewhat anterior to the pancreatic duct. From the duodenum it runs to the left and downwards, and soon divides into two or more branches, one of which joins the pancreatic duct, the others pass down and receive the ducts from the lower part of the head. It is generally supposed that the current flows from this into the main duct, and not into the duodenum, as
