Foregut (spleen and pancreas) Flashcards
what are the 4 parts of the pancreas
head
neck
body
tail
where does the head of the pancreas lie
in concavity of the duodenum
the uncinate process of the pancreas lies where
posterior to the superior mesenteric vessels
where does the neck of the pancreas lie
anterior to origin of superior mesenteric artery
where does the body of the pancreas lie
passes laterally and superiorly to left
where does the tail of the pancreas lie
passes in lienorenal ligament and into contact with hilar surface of spleen
the pancreas is ___peritoneal
retroperitoneal
what are the relations of the anterior surface of the pancreas
transverse colon
stomach
what are the relations of the posterior surface of the pancreas
bile duct portal vein splenic vein IVC aorta superior mesenteric artery Left psoas left suprarenal gland left kidney spleen
the main duct draining exocrine secretions of the pancreas goes from where to where
from tail to ampulla of Vater in 2nd part of duodenum
if an accessory pancreatic duct exists, it will open where
into 2nd part of duodenum, at a site superior to the ampulla
what is the arterial supply of the pancreas
dorsal pancreatic artery and branches
superior and inferior pancreaticoduodenal arteries
the dorsal pancreatic artery comes from
splenic artery
the superior pancreaticoduodenal artery comes from
gastroduodenal artery
the inferior pancreaticoduodenal artery comes from
superior mesenteric
pancreatic veins drain where
into splenic or superior mesenteric veins and from there to the portal system
lymph from the pancreas drains to where
local nodes then then to pre-aortic nodes at T12 (coeliac) and L1 (superior mesenteric)
pain from the pancreas is referred where
epigastric region
autonomic nerves of the pancreas are from where
coeliac plexus and superior mesenteric plexus
true/false
the spleen is the largest single mass of lymphoid tissue in the body
true
where does the spleen lie
inferior to ribs 9-11 in the left hypochondrium
the spleen lies ____ to the stomach
posterior
spleen is very similiar size to kideny - how is the spleen differentiated from the kidney
hilum of spleen doesnt have a ureter
what carries short gastric and gastro-epiploic vessels
gastro-splenic ligament
do the splenic artery and vein always pass into/out of hilum of spleen
usually but some variations - some vessels may pass into an upper or lower pole of the spleen
what does the lienorenal ligament to left kidney carry
splenic artery and vein
hilum of spleen is in contact with what
tail of pancreas
what is the largest branch of the coeliac axis
splenic
the splenic artery passes along where to reach hilum of spleen
along superior surface of pancreas
describe the course of the splenic vein
exits the hilum and passes immediately posterior to the pancreas - joints with superior mesenteric vein to form portal vein
what 2 vessels form the portal vein
splenic vein and superior mesenteric
where does the inferior mesenteric vein drain
into the splenic vein at some point prior to formation of portal vein
nerves of spleen come from
coeliac plexus
lymph from spleen drains
to pancreaticosplenic nodes then coeliac
