Morphological Studies on the Blood Vessels and Nerves of the Crus of the Brown Bear (Ursos Arctos)

Abstract

The purpose of the present research is to investigate the major arteries, veins, and nerves of the crus in the brown bear through macro anatomical dissection and contrast radiography. The pelvic limbs of 4 bears were included in the study. The limbs were removed from the trunk and the vessels and nerves were dissected and photographed. For the radiography barium sulfas solution was introduced through the femoral artery and images in cranio-caudal and medio-lateral projection were made. The main arteries, veins and nerves and their branches supplying the structures of the crural region were identified and compared to the dog, cat and human.
