Worksheet 5 - The duodenum, pancreas and spleen Flashcards
which arteries supplying the pancreas branch from the gastroduodenal artery?
anterior + posterior superior pancreaticoduodenal arteries
inferior pancreatico-duodenal arteries
which 2 arteries supplying the pancreas branch from the splenic artery? are these anterior or posterior to the pancreas?
dorsal pancreatic artery
greater pancreartic artery
posterior
which 2 pancreatic veins drain into the hepatic portal vein
superior + inferior pancreatico-duodenal veins
which part of the pancreas is drained by the pancreatic veins, and what vein does it drain into?
body/neck
splenic vein
4 parts of the duodenum
superior, descending, horizontal, ascending
which part of the duodenum is intraperitoneal
superior duodenum
what is the only way to differentiate the duodenum fro the jejunum?
the duodenum is retroperitoneal, the jejunum has a mesentery
which blood vessel supplies the upper duodenum? what is the origin?
superior pancreatico-duodenal = gastroduodenal
which blood vessel supplies the lower duodenum? what is the origin?
inferior pancreatico-duodenal = SMA
why is there dual supply to the duodenum?
the duodenum has 2 embryological origins
where is the uncinate process?
posterior to SMA+V, but anterior to aorta as the head extends
which vein is formed at the posterior neck of the pancreas?
hepatic portal vein
what does the tail of the pancreas run through to reach the spleen?
lienorenal ligament
what is the lienorenal ligament?
ligament from the spleen to the kidney
in relation to the pancreas, where does the splenic artery run?
superior border
which organ has both exocrine + endocrine function
pancreas
is the pancreatic duct endocrine or exocrine?
exocrine
what does the exocrine pancreas secrete?
digestive enzymes
the pancreatic duct joins the common bile duct to form..
the hepatopancreatic ampulla of Vater
where does the ampulla open into the duodenum?
major duodenal papilla
what does the accessory pancreatic duct drain?
the uncinate process
where does the accessory pancreatic duct drain into?
the duodenum
what does the major duodenal papilla mark the boundary between?
duodenum - embryological change from foregut into midgut
which abdominal area does the spleen lie in
left hypochondrium
at what vertebreal level and plane does the spleen hilium lie?
L1 - transpyloric plane
which ribs is the spleen in between?
9-11th
what does the spleen hilum lie between?
left kidney and stomach
branches of the splenic artery supply which organ?
pancreas
from which vertebral levels does the abdominal aorta extend to and from?
T12-L4
