The femoral artery and its branches in the baboon Papio anubis

The aim of the research was to examine the anatomy of the arterial system in the inguinal region, hip and thigh of Papio anubis. No description of this was found in the available scientific literature, although, at the same time, the baboon is considered to be a good animal model in biomedical research. Macroscopic anatomical research was carried out on 20 hind limbs (10 cadavers: 9 male and 1 female) of adult Papio anubis and the results were then compared with the anatomy of the arterial hind limb systems of other apes as described in the literature. The circulatory system of the whole body was filled with coloured latex via the common carotid artery and internal jugular vein, and traditional methods were then used to prepare the vessels. The arterial system in the hind extremity of Papio anubis was recorded. The anatomical names of human arteries were used as well as the names of those of apes as applied in the literature. The femoral artery was the only artery supplying the hind limb of Papio anubis. It started under the inguinal ligament as a continuation of the external iliac artery. It went down and divided into the popliteal artery, which coursed in the popliteal fossa, and the saphenous artery, which passed on the medial side of the thigh and leg. The number of smaller branches and the way in which they issued from the larger arteries were documented. The external diameter and length of the hind limb arteries were measured. It was observed that the cutaneous branches of the femoral artery supplied the inguinal and genital regions and the abdominal wall, while the deep artery of the thigh was the main vessel of the hip and thigh.
