The embryology also explains the strange zig-zag course of the main pancreatic duct and the occasional appearance of an accessory pancreatic duct. The uncinate process, unlike the remainder of the organ, passes posteriorly to the superior mesenteric vein (it can pass posteriorly to the superior mesenteric artery , but this is less common).
An uncinate process is a hook-shaped projection or protuberance from a bone or organ. It may refer to: Uncinate process of ethmoid bone, a process located in the nasal cavity

The pancreatic duct is generally regarded as abnormally enlarged if being over 3 mm in the head and 2 mm in the body or tail on CT scan. [9] Pancreatic duct or parts of pancreatic duct can be demonstrated on ultrasound in 75 to 85% of people. [10] Pancreatic ductal carcinoma is a common form of pancreatic cancer.
