pancreas

The head is the expanded medial part of the pancreas. It lies directly against the descending and horizontal parts of the C-shaped duodenum which wraps around the pancreatic head. Projecting inferiorly from the head is the uncinate process, which extends posteriorly towards the superior mesenteric artery. Continuing laterally from the head is the neck, a short structure of approximately 2 cm that connects the head with the body. Posterior to the neck are the superior mesenteric artery and vein and the origin of the hepatic portal vein – formed by the union of the superior mesenteric and splenic veins.
