The second part of the duodenum
|
|
What are the 4 parts of the duodenum?
|
Ascending, superior, descending, inferior
|
|
What artery lies directly behind the first portion of the duodenum?
|

|
|
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.
