Development of pancreas?
Ventral budFrom the hepatic diverticulum and it gives rise to the lower part of the head and uncinate process.
Dorsal bud
From the dorsal aspect of the duodenum and gives rise to upper part of the head, neck, body and tail.
Peritoneal relation of pancreas?
All is retroperitoneal except for the tail -
Blood supply of pancreas?ArterialVenous<ul><li>Superior pancreaticoduodenal artery (from gastroduodenal artery) supply head</li><li>Inferior pancreaticoduodenal artery (from SMA) supply head & uncinate process</li><li>Pancreatic branches (from splenic artery) supply tail & body</li></ul><ul><li>Superior pancreaticoduodenal vein</li><li>Inferior pancreaticoduodenal vein</li><li>Veins drain to splenic vein</li></ul>
Course of splenic arteryArise from celiac, pass above pancreas, behind stomach (separated from it by lesser sac), lienorenal ligament then ends by terminal branch in splenic hilum.
Describe ductal drainage system of pancreas?Main pancreatic duct (of Wirsung):drains head, body and tail $\rightarrow$ opens into major duodenal papilla.Accessory pancreatic duct (of Santorini):drains the uncinate process $\rightarrow$ opens into minor duodenal papilla.
Vessel presents behind body of pancreas?Splenic vein
Space between stomach and pancreas?Lesser sac
Vessel present behind neck?Portal vein
Peritoneal relations of the duodenum?The first part of the duodenum lies within the peritoneum, but its other parts are retroperitoneal.
Vessels present in front and behind the third part of duodenum?In frontSuperior mesenteric artery & veinBehindIVCAortaRight gonadal vein
Hepatic artery runs in which part of peritoneum?Lesser omentum
