Morphological Studies of the Pancreas in the White Wistar Rat

Abstract

Of all the subsidiary glands of the digestive apparatus, the pancreas represents an important issue in the animal economy. This fact made us to investigate it on a macroscopic scale. We had in view the location (topographical situation) and the morphologic aspect. Then, we continued with microscopic investigations. We observed in parallel 7 white rats and registered the anatomohistological data about the pancreas of this species. The topography of the pancreas in rat does not present great differences compared to what is already known in other species, and especially in the laboratory animals. We did not noticed major morphological differences. The excretory apparatus of the pancreas is complex, being represented by a canalicular system out of which the two pancreatic ducts will form: Wirsung - the main one and Santorini - the accessory pancreatic duct. The endocrine pancreas of the rat presents like in other species the two types of cells B and A.
