510 A MANUAL OF ANATOMY. 



The Hepatic Artery, 



Next in size, comes off from the right side of the cceliac 

 axis. It takes a direction to the right and upward to the liver. 



Branches. (a) The pyloric. This is given off opposite 

 the pylorus, passes to this end of the stomach, turns to the 

 left and joins the terminal branches of the gastric. (<) The 

 g-astroduodenalis, really one of the branches of bifurcation 

 of the hepatic, descends behind the pylorus. See its fur- 

 ther course below, (c) The cystic. This supplies the gall 

 bladder, (d) The terminal branches, right and left, to 

 supply their respective lobes of the liver. 



The relations of the hepatic artery, duct, and portal vein 

 have been given. See Gastrohepatic Omentum, page 492. 

 (e) The hepatic gives off several small pancreatic branches 

 to that gland. 



DISSECTION. 



Divide the anterior layer of the greater omentum just below the greater 

 curvature of the stomach. Turn the stomach up over the chest and fasten it 

 there with chain hooks. Complete the dissection of the splenic and gastro- 

 duodenal arteries. Trace the common bile duct and portal vein as far as 

 possible. Clean the anterior surfaces of the pancreas, duodenum, and the 

 beginning of the superior mesenteric artery. 



The Splenic Artery. Fig. 105. This is the largest of 

 the cceliac branches. It passes behind the stomach toward 

 the left to supply the spleen. It gives off (a) numerous 

 small branches to the pancreas as it courses along its upper 

 border, called the pancreaticse parvae. (&) A large artery, 

 the pancreatica magna, to the same gland, (c) Then the 

 left gastro-epiploic which follows the greater curvature of 

 the stomach between the layers of the great omentum, from 

 left to right to inosculate with the right artery of this name. 

 (d) The vasa brevia, several branches to the fundus of the 

 stomach, which anastomose with the gastric, (e) The ter- 

 minal branches to the spleen itself.
