Relations of mesenteric vessels to head of pancreas

The stomach has been retracted upward to show the gastroduodenal artery which passes downward behind the pylorus. Pyloric branches of this artery (4) have been dissected. The course of the superior mesenteric vein and artery in relation to the head and uncinate process of the pancreas has been displayed.

1. Common hepatic duct (in dissected liver)
2. Pylorus
3. Gastroduodenal artery
4. Pyloric branch of gastroduodenal artery
5. Upper pointer: Right gastroepiploic artery (cut off) Lower pointer: Epiploic branch of right gastroepiploic artery
6. Head of pancreas
7. Remnant of right border of greater omentum
8. Duodenum (covered by connective tissue)
9. Stomach
10. Body of pancreas
11. Jejunum (cut off)
12. Middle colic artery
13. Duodenal branches of jejunal artery
14. Band of peritoneum preserved from earlier dissection
15. Superior mesenteric artery (note mesenteric plexus of nerves associated with artery)
16. Superior mesenteric vein
