All are true about splenic artery EXCEPT
Correct Answer: It lies posterior to superior border of pancreas
Description: (A) It lies posterior to superior border of pancreas# SPLEEN is supplied exclusively from the splenic artery.> This is the largest branch of the coeliac axis and its course is among the most tortuous in the body.> From its origin the artery runs a little way inferiorly, then turns rapidly to the left to run initially horizontally above the level of the neck of the pancreas, before ascending as it passes more laterally.> It is less steeply inclined than the body and tail of the pancreas and so comes to lie posterior to the superior border of the gland.> It lies in multiple loops or even coils which appear above the superior border of the pancreas and descend to lie behind the gland.> Splenic artery lies anterior to the left kidney and left suprarenal gland and runs in the splenorenal ligament posterior to the tail of the pancreas.> It divides into two or three main branches before entering the hilum of the spleen.> As these branches enter the hilum they divide further into four or five segmental arteries that each supply a segment of the splenic tissue.> There is relatively little arterial collateral circulation between the segments, which means that occlusion of a segmental vessel often leads to infarction of part of the spleen.> End arteries -Arteries that do not form anastomoses -Only one route -E.g.: Renal artery, Splenic artery> Functional end arteries -Have small anastomoses -E.g.: Coronary arteries
