The major intrinsic pancreatic ducts of the rhinoceros



A first-time account is given of the parenchymal subdivisions and related duct system of the pancreas in Didermocerus, Diceros and Ceratotherium. In each of these rhinoceros forms a small, superficial portion only of the caput pancreatis is drained by a Santorini duct opening directly into the duodenum. The remainder of the pancreatic parenchyma is drained principally by a transverse and an ascending duct, from whose union arises a short Wirsung duct which enters the duodenum through an intermediary Vaterian ampulla situated within a prominent papilla duodeni.
