Its part of the lesser omentum so does it attach to greater or lesser curvature?
How are they different?
pyloric orifice (lower openin) – true anatomical sphincter, formed by thickening of circular muscle
Where is this?
near cardiac opening
paired: middle suprarenal artery, renal artery, ovarian/testicular artery
paired: inferior phrenic arter, lumbar artery
left gastric artery, splenic artery, common hepatic artery
What does it supply?
-left and right gastroepiploic (branch of splenic and gastroduodenal)
-short gastric arteries (branch of splenic)
What about the greater curvature
right and left gastroepiploic arteries
What is the left lobe composed of “functionally” ?
cuadate and quadrate are actually part of left lobe
How do we count in this system?
start at cuadate lobe and count counterclockwise (should get 8)
What about the spots with no coronary ligament…what are these called?
-these are called “bare areas” b/c not covered by peritoneum and liver directly touches diaphragm
portal vein = 70 %
Portal vein = about 50 %
What veins make up the portal vein?
-superior mesenteric and splenic vein unite to form portal vein
-cystic duct joins with common hepatic duct to form common bile duct
-common bile duct is joined with main pancreatic duct
– enters second part of duodenum via hepato-pancreatic ampulla (aka vater)
hepatopancreatic sphincter ( located at hepatopancreatic ampulla…aka Vater)
located between stomach and diaphragm
sheltered by lower ribs
What is the one other one many forget…??
spleno-renal = splenic artery, vein, & tail of pancreas
What artery contributes to the spleen’s major blood supply?
What is the accessory spleen?
– splenic artery
-splenic tissue found near hilum ( 20% of pop)
