SUPERIOR MESENTERIC ARTERY. 301 



One of these, larger than the rest, follows the course of the pancre- 

 atic duct, and is called pancreatica magna. 



The Vasa brevia are five or six branches of "small size which pass 

 from the extremity of the splenic artery and its terminal branches, 

 between the layers of the gastro-splenic omentum, to the great end 

 of the stomach, to which they are distributed, inosculating with 

 branches of the gastric artery and of the gastro-epiploica sinistra. 



The Gastro-epiploica sinistra appears to be the continuation of 

 the splenic artery ; it passes forwards from left to right, along the 

 great curve of the stomach, lying between the layers of the great 

 omentum, and inosculates with the gastro-epiploica dextra. It is 

 distributed to the greater curve of the stomach and to the great 

 omentum.

The SUPERIOR MESENTERIC ARTERY, the second of the single 

 trunks, and next in size to the creliac axis, arises from the aorta im-

 verse fissure. 3. The gall bladder. 4. The stomach. 5. The entrance of the O3so- 

 phagus. 6. The pylorus. 7. The duodenum, its descending portion. 8. The trans- 

 verse portion of the duodenum. 9. The pancreas. 10. The spleen. 11. The aorta. 

 12. The coeliac axis. 13. The gastric artery. 14. The hepatic artery. 15. Its pyloric 

 branch. 16. The gastro-duodenalis. 17. The gastro-epiploica dextra. 18. The 

 pancreatico-duodenalis, inosculating with a branch from the superior mesenteric artery. 

 19. The division of the hepatic artery into its right and left branches; the right giving 

 off the cystic branch. 20. The splenic artery, traced by dotted lines behind the stomach 

 to the spleen. 21. The gastro-epiploica sinistra, inosculating along the great curva- 

 ture of the stomach with the gastro-epiploica dextra. 22. The pancreatica magna. 

 23. The vasa brevia to the great end of the stomach, inosculating with branches of the 

 gastric artery. 24. The superior mesenteric artery, emerging from between the pan- 

 creas and the transverse portion of the duodenum.
