Sapajus libidinosus is a new World primate commonly known as capuchin monkey, geographically distributed throughout South America, has characteristics of restlessness and ability to manipulate tools to obtain food. This study aimed to describe the morphology of the dural sinuses of S. libidinosus through a comparative perspective. We used 3 adult male from the Federal University of Goiás, Brazil, fixed in aqueous 10% formaldehyde. The longitudinal fissure in the brain extends deeply and divides the organ into two left right hemispheres, The frontal and parietal lobe presents relatively smooth surface, but with well-defined gyri and sulci. In the occipital lobe, however, smooth surface aspect prevails. We observed eight sinuses of the dura mater, sagittal dorsal, ventral sagittal, transverse, straight, sigmoid, basilar and temporal which corresponds generally to the descriptions of other primates as Pan, Papio and man. Furthermore, parietal sinus similar to Saimiri sciureus and absence of sinus occipital, as in Macaca mullata, were also recorded. In the capuchin monkey, intracavernous, sphenoparietal, superior petrosal and inferior petrosal sinuses, which are described in Pan, Papio and Man, were absent. Taken together, these data point to a possible grater evolutionary proximity to man of Papio and Pan as compared to Cebus. |
