ABSTRACT: Objectives: To underscore the importance of using latex injection technique for teaching and learning non-human primates arterial vascularization. Methods and Results: We used ten adult animals of Callithrix penicillata (Black-tufted-ear-marmoset), five males and five females, coming from a breeding of wild animals, located in Atibaia/SP, died by natural causes. Those animals after receipt at the Laboratory of Anatomy of Domestic and Wild Animals, College of Veterinary Medicine and Animal Science of Sao Paulo (FMVZ-USP) where dissected in the medial aspect of left pelvic limb for access the femoral trigone region, showing the femoral left artery. This was then cannulated and prepared for red neoprene/latex 650 injection to visualize primates arterial system. Subsequently the animals were placed in pots containing formaldehyde 10% for at least 72 hours for later dissection. After the fixation period, was held the opening of the abdominal and pelvic cavity through an incision in the linea alba and the photo documentation of the arterial system. For this reason, the branches of the pelvic and abdominal aorta, their anastomoses, divisions and anatomical variations from animal to animal could be observed (Figure 1). Conclusions: The use of latex injection to visualize the arterial system of nonhuman primates has enable a real teaching and learning about architecture, topography and anatomical variations in the animals analyzed. Therefore, this study suggests that this technique should be used more often, especially regarding the anatomy of nonhuman primates in order of their importance as basic science of vascular study, both for the morphology of the species as to the comparative anatomy.
