The pancreatic notch, or the incisura pancreatis, is a notch that separates the pancreas’ uncinate process. This process is a prolongation at the left and lower borders of the head of the pancreas-from the neck of the pancreas. It’s main function is to make signs that control the pancreatic cell differentiation. The pancreatic notch is tucked between the pancreas’ omental tuber (in the main body of the pancreas, away from the tail) and the duodenum.
