The cocliac axis arises high up, from the front of the aorta, 

 runs forward for about half an inch, and then divides into 

 three branches, coronary, hepatic, and splenic. [843] 



The coronary (co3liac axis) runs to the left and then bending 

 sharply, along the lesser curvature of the stomach, in the lesser 

 omentum, to join the pyloric branch of the hepatic. Branches ; 

 oesophageal, to the oesophagus ; gastric, to the stomach. [844] 



The splenic (coeliac axis) runs along the upper border of the 

 pancreas, across the suprarenal body and kidney, and in the 

 lieno-renal ligament, dividing into branches which enter the 

 hilus of the spleen. Branches. Pancreatic, small branches 

 (pancreatica parvse) to the gland and a large one (pancreatica 

 magna) running in it from left to right, just above the duct. 

 Vasa brevia, small branches to the left end of the stomach. 

 Left gastro-epiploic, running along the greater curvature of 

 the stomach from left to right, in the great omentum, to join 

 the right gastro-epiploic. [844] 



The hepatic (coeliac axis) runs along the head of the pan- 

 creas, then forward in the right pancreatico-gastric fold to the 

 duodenum, and then upward in the small omentum in front of 

 the portal vein ; it divides at the transverse fissure of the liver 

 into the right and left hepatic. Branches. Pyloric, to the py- 

 lorus and lesser curvature of the stomach, joining the coronary. 

 Gastro-duodenal ; descending behind the duodenum this di- 

 vides into two branches ; one (right gastro-epiploic) runs along 

 the greater curvature of the stomach; the other (superior pan- 

 creatico-duodenal) runs between the duodenum and head of 

 the pancreas, supplying both. Left hepatic; after supplying 

 the Spigelian lobe, this enters the left end of the transverse 

 fissure. Right hepatic; after running behind the cystic duct 

 and sending a branch (cystic) along it to the gall bladder, this 

 enters the right end of the transverse fissure. [845] 



The superior mesenteric arises from the front of the aorta 

 just below the coeliac axis, descends between the pancreas and 

 duodenum, enters the mesentery, and then curves downward
