Comparative anatomy of the pelvic vessels in the bearded capuchin (Sapajus libidinosus) and baboons, apes and modern humans.
Cebus/Sapajus has shown high cognitive and manipulatory behaviour as well as intermittent bipedalism. Although the function of the muscles and bones of this genus has been widely investigated, the arterial system that supports these tissues has not been studied in much detail, and a full description of the blood vessels of the pelvis is still missing. Therefore, we studied the vessels of the pelvis of Sapajus libidinosus in terms of their origin, distribution and muscle irrigation and compared them with those of other primates available in the literature. In general, the distribution pattern and origin of arteries in the pelvis of the bearded capuchin are more similar to those of baboons compared to other primates. This similarity may be because both have a tail, a similar body shape and use, preferentially, quadrupedal movement.
