Morphological study of the pancreatic duct system in chinchilla (Chinchilla laniger Molina).

Abstract

The aim of our investigation was analysis of the morphology of the pancreatic duct system in chinchilla. Investigation was carried out on twenty adult individuals of either sex. Macromorphological studies of pancreatic duct system were performed using colored latex. The histological studies were performed paraffin slides with H&E staining method. Photography documentations were prepared using a Nikon Digital Sight SD-L1 System. The pancreas in this species is formed of three irregular flattened parts or lobes. The main accessory duct was not observed. The accessory pancreatic duct was the only duct to drain pancreatic secretion into the duodenum on the minor duodenal papilla. The histological structure of these ducts does not differ from the general scheme. Our investigation demonstrated significant anatomical variability of the pancreatic duct system in chinchilla which is not always accurately described in literature.
