Ascending, superior, descending, inferior
What artery lies directly behind the first portion of the duodenum?
Gastroduodenal artery
Where does the common bile duct and pancreatic duct enter the duodenum?
The posteromedial aspect of the second part of the duodenum.
What is the name of the dilation formed by the junction of the common bile duct and the main pancreatic duct?
- the hepatopancreatic ampula,

-sphinter of oddi/vater
What is the ligament of Treitz?
A well marked peritoneal fold at the junction of the 4th part of the duodenum with the jejunum.
How does the jejunum differ in appearance from the ileum?
The jejunum has:
- thicker walls
- a larger diameter
- more vascular
- larger and more developed plicae circularis
-longer vasa rectae
State the portion of the large intestine that has the widest diameter!
The cecum and as a result it is the site most likely for colonic perforation
What is the arterial supply of the cecum?
The anterior and posterior cecal arteries --> a branch of the ileocolic artery.
State 3 features that differentiate the large intestine from the small intestine.
- Teniae coli
- Haustra
- Apependicies epiploicae
What structure marks the end of the small intestine?
The ileocecal valve
Branches of the inferior mesenteric artery:
Left colic (1st branch)

Sigmoidal (2nd branch)

Superior rectal (3rd branch)
What are teniae coli?
3 thin bands of muscle which run longitudinally along the entire length of the ascending, transverse, descending colon
What are haustra?
Sacculations of large bowl which are created by contractions of taenia coli
What are appendicies epiploica?
small fat-filled peritoneal sac along the taeniae coli
What arteries supply the ascending colon?
The ileocolic and the right colic arteries (both branches of the superior mesenteric artery)
What is the marginal artery of Drummond?
The marginal artery of Drummond is a continuous arterial chain linking the vascular arcades of the entire colon.
What is the location of Griffith's point?
Griffith's point is located at the splenic flexor, the junction of the SMA and IMA vascular territories.
What is the location of Sudeck's point?
Sudeck's point is at the junction of the sigmoid colon and the rectum.
The main pancreatic duct usually joins what structure?
Common bile duct
What major vessels travels along the pancreas?
Splenic A
What major vessel supply the head of the pancreas?
superior and inferior pancreaticduddenal arteries
What 2 arteries supply the body and the tail?
- Greater pancreatic A

- Dorsal pancreatic A
Why must the duodenum be removed if the head of the pancreas has cancer?
they share the same blood supply
What landmark determines the neck of the pancreas?
- the superioro mesenteric artery and a cancer here determine as to whether a pancreatic cancer is resectable.
