Answers

1. c

Anterior and Posterior superior Pancreatic vessels are derived from coeliac artery.

Anteior and posterior Inferior pancreatic vessels are derived from Superior Mesenteric artery.

Splenic artery supplies the body and tail of pancreas. Dorsal pancreatic artery usually arises from the splenic artery, near its origin from the celiac trunk. A right branch of the dorsal pancreatic artery supplies the head of the pancreas and usually joins the posterior arcade.

The gastroduodenal artery gives origin to the supraduodenal, retroduodenal, and posterior

superior pancreaticoduodenal (PSPD) arteries. The gastroduodenal artery ends by dividing into the right gastroepiploic and anterior superior pancreaticoduodenal (ASPD) arteries.

PSPD is a branch of gastroduodenal and not Superior mesenteric artery

The anterior inferior pancreaticoduodenal artery arises from the SMA at or above the inferior margin of the pancreatic neck
