The tail of the pancreas is slender and stretches left to the spleen’s lower part of the gastric surface, resting in the phrenicolienal ligament. The left colic flexure is close to the tail of the pancreas. It’s close to the hilum of the spleen.
The only portion of the pancreas that holds pancreatic polypeptide (PP) cells is the pancreatic tail. The function of these cells is to secrete pancreatic polypeptide to plan the release of exocrine and the islet enzyme. The tail’s periphery houses the cells. In the central part of the tail and the rest of the pancreas have beta cells and delta cells (insulin secretory and somatostatin secretory respectively).
