Abstract
The present study aimed to investigate the morphological features of the pancreas and duodenum of the adult males and females guinea pigs. Eight animals of each sex were collected to conduct this project. The selected organs were photographed in situ and macro morphometric measurements were conducted on them. Gross findings revealed that the pancreas of guinea pig was of compact type, of two lobes (right and left) connected by large central part (body). The organ drains the pancreatic secretion toward the last part of the ascending duodenum via minor pancreatic duct with absence of major pancreatic duct. The duodenum of the guinea pig was very short and V-shaped. The beginning of the duodenum contains duodenal papilla in which found central orifice for the exit of bile secretions of the common bile duct. In conclusions, the present findings showed the presence of only one minor pancreatic duct and such result was significantly different than most rodents by having major pancreatic duct. The duodenum in the studied guinea pigs was characteristically very short and V-shaped differently to other animals that have U-shaped and long duodenum.
Highlights
Domestic guinea pigs (Cavia porcellus) are a descendant of the wild cavy (Cavia aperea) which is considered one of the common rodents lived in South America
The compact type of pancreas of guinea pigs was recorded in humans and animals such as monkeys, minipigs, dogs, cats and hamsters [16, 17, 18]
In some animal species such as pig and ox, the right pancreatic lobe appeared closely related to the descending duodenum [22] and such observation was as same as in the current studied guinea pig, whereas, oppositely in the rabbit’s pancreas the duodenal or right lobe observed closely adherent to the ascending limb of the duodenum [15].The body of the pancreas represented the connecting part of the portal vein through it which was considered a good vessel marker in the previous researches [23, 24]
Summary
Domestic guinea pigs (Cavia porcellus) are a descendant of the wild cavy (Cavia aperea) which is considered one of the common rodents lived in South America. They are characterized by their stocky body, short neck and limbs and they are more closely related to porcupines than mice and rats [1, 2]. They are widely distributed because of its popularity as a pet and a food source. Pancreas is an organ of special interest from a medical viewpoint
