Duodenum, Pancreas and Spleen Flashcards
Which direction does each part of the duodenum travel in?
First: Short ascent to the right (L1)
Second: Descends down to L3
Third: Horizontal to the left, crossing IVC, aorta and L3
Fourth: Ascends to left of aorta up to pancreas then to duodenal-jejunal junction
The first part of the duodenum is contained in which ligament?
Hepatoduodenal ligament
At the point of the duodenal-jejunal junction, the intestine is supported by a thin slip of muscle. What is it’s name and what does it do?
Suspensory muscle of diaphragm
When it contracts, the flexure widens, allowing food to enter the jejunum
What is the only distinguishing feature of between the duodenum and jejunum?
Duodenum is retroperitoneal, jejunum has a mesentery
The duodenum has dual arterial supply. Which arteries supply the duodenum?
Coeliac trunk: gastroduodenal, superior pancreaticoduodenal
Superior mesenteric: Inferior pancreaticoduodenal
What is attached to the anterior surface of the pancreas?
Transverse mesocolon
Which vein is formed behind the neck of the pancreas?
Hepatic portal vein
The tail of the pancreas passes in the __?__ to reach the spleen
splenorenal ligament
Which artery follows along the upper border of the pancreatic body and tail?
Splenic artery
The exocrine component of the pancreas is responsible for secreting various __1__. These are collected into a series of ducts which open in a principal __2__. This then joins the __3__ to form the __4__ ampulla (of Vater). The ampulla opens in the duodenum at the __5__. The __6__ (draining the uncinate process) also opens in the duodenum, about 2cm proximal to (5).
1) digestive enzymes
2) pancreatic duct
3) common bile duct
4) hepatopancreatic
5) major duodenal papilla
6) accessory pancreatic duct
The major duodenal papilla marks the boundary between which two subdivisions of the gut?
Fore- and midgut
What is found at the tail of the pancreas?
Spleen
What structure originates from the body of the pancreas?
Transverse mesocolon
Which part of the pancreas is found in the concavity of the duodenum?
Head
Superior mesenteric artery and vein lie anteriorly to which part of the pancreas?
Uncinate process
