Morphology of the walls of the cavernous sinus of Cebus apella (tufted capuchin monkey)

The morphology of the dura mater and its relatioship with the structures of the cavenous sinus were analyzed in five tuftel capuchin monkeys (Cebus apella) using histological sections, showing that the walls of the cavenous sinus of this species are similar to those of other primates, including man. Except for the medial wall of the cavernous sinus, the remaining walls consist of two distinct dura mater layers. The deep layer of the lateral wall of the cavernous sinus is contiguous to the sheath of the oculomotor, trochlear and ophtalmic nerves. Arterioles, venous spaces, neuronal bodies and nervous fiber bundles are found on this lateral wall.
