Uncinate process of pancreas

In the head of the pancreas, the angle of junction of the lower and left lateral borders forms a prolongation, termed the uncinate process.

During the embryonic development of the distal foregut, the dorsal and ventral pancreatic bud fuses after the stomach rotates. The dorsal pancreatic bud becomes the head, body and tail of the pancreas and the the ventral pancreatic forms the uncinate process.
