Distribuição dos nervos da coxa de Cebus Libidinosus (Rylands et al., 2000)

Abstract

Non-human primates have constituted an important group among animals subjected to various studies, such as ethological and paleontological studies who have revealed changes in anatomical structures linked to the evolution of primates and the detailed knowledge on their anatomy may represent an important factor for their preservation and protection. Aimed to identify the distribution of the femoral, saphenous, obturator and sciatic nerve of the pelvic limb of Cebus libidinosus (C.l.). In general, the enervation model of the four primates, men, baboons, chimpanzees and C.l. is identical, but in specific terms, the differences in enervations indicate evolution divergence closer to the branch of baboons in the evolutionary tree, and these data corroborate other comparative studies in relation to the same primates to vessels, muscles and nerves. In conclusion, the sciatic nerve sends branches to the biceps femoris muscle, semitendinous, semimebranosus and accessory and to the ischiofemoral muscle, in the distal third, this nerve is divided into tibial, sural cutaneous medial and common fibular nerves; the femoral nerve sends branches to the sartorius muscle, vastus intermedius muscle, vastus medialis muscle, to the vastus lateralis muscle and branches to the rectus femoris muscle and sends the saphenous nerve. The obturator nerve provides branches to the pectineus muscles, adductor brevis muscles, adductor magnus muscles, adductor longus muscle and glacilis muscle.
