SPLEXIC ARTERY. 409 



the upper border of the pancreas, and divides near the spleen into several 

 branches. The largest of these enter the fissure in that organ, and are dis- 

 tributed to its substance ; three or four are reflected towards the bulging 

 end of the stomach, upon which they ramify.

 (from Tiedetnann). \ 



The stomach and liver are turned upwards so as to show their lower surface. The 

 jejunum is divided at its commencement, a, lower surface of the right lobe of the liver ; 

 b, left lobe ; c, cardiac oiifice of the stomach ; d, pylorus ; c, first part, /, second or 

 descending part, and g, third or lower part of the duodenum ; h, commencement of the 

 jejunum emerging from behind the superior mesenteric artery ; i, the head, and &, the 

 body of the pancreas; Z, the spleen ; 1, 1, right and left inferior phrenic arteries passing 

 from the aorta upon the crura of the diaphragm ; 2, placed on the aorta close to the 

 coeliac axis; 3, 3', the coronary artery; common hepatic; 4', proper hepatic artery ; 

 4", cystic branch ; 5, gastro- duodenal giving the inferior pyloric ; 5, on the great curva- 

 ture of the stomach, the right gastro-epiploic ; 6, pancreatico-duodenal ; 7, common 

 splenic ; 7', proper splenic ; 7", one of the vasa brevia to the stomach ; 8, 8, left gastro- 

 epiploic artery uniting with the right on the great curvature of the stomach ; 9, trunk of 

 the superior mesenteric artery, giving a small branch to join the pancreatico-duodenal ; 

 10, inferior mesenteric. 



BRANCHES. (a) Pancreatic brandies, variable in size and number, are 

 given off whilst the artery is passing along the pancreas, the middle and 

 left part of which they supply with vessels. One of larger size not unfre- 

 quently runs from left to right in the direction of the pancreatic duct, and 

 is called pancreatica magna. 



(6) The splenic branches are the proper terminal branches of the artery ; 

 they are five or six, or even more, in. number, and vary in length and size ; 

 they enter the spleen by the hilus or fissure in its concave surface, and 

 ramify within that organ. 



(c) The short gastric branches (vasa brevia) vary from five to seven in num- 

 ber ; they are directed from left to right, some issuing from the trunk of the 

 splenic artery, others from its terminal branches : they reach the left ex- 

 tremity of the stomach, where they divide and spread out between the coats, 

 communicating with the coronary and left gastro-epiploic arteries.
