RESUMO

The gender Cebus, represented by four species and several subspecies, its found geographically distributed since Central America up to the south of South America however, its anatomy is still little well-known. Its from easy adaptation and can survive in small forests and restingas, but the continuous destruction of its habitat has been threatening, in a progressive way, its survival, what point the importance of these kinds of study. Considering still the important cerebellums function at the control and maintenance of body equilibrium and muscle tonus, as well as the estabilishement of posture, harmony and movements coordenating, the present work proposes to analyze, on C. apella, macro and mesoscopically, the disposition of structures at its cerebellum. This way the objective is to know better C. apellas cerebellum, what will allow us to weave related to its functional potentialities comparing to other no-human primates, domestic mammals and human. Its was used 20 animals, 16 to macroscopic analysis and 4 mesoscopic fixed and kept in of formaldehyde 10%, belonging to the research of Professor Dr. Zenon Silva, at Universidade Federal de Uberlândia, MG. After convenient prepare of each part, it was macroscopically observed the cerebellum hemispheres that seems little developed in relation to the worm. At cerebellums body, it was identified three portions, the previous lobe, posterior and floculonodular, like this respectively constituted: língula, central lobule plenty developed, as well as its wings, cúlmen and previous quadrangular lobule, declive, posterior quadrangular lobule, worms leaf, semilunar lobules well characterized at equatorial region of the hemispheres, being one above and one below, túber, pyramid, well developed tonsil and biventer lobule also well demarcated. Its very obvious the primary fissure (between the previous and posterior lobe), horizontal (between the superior and inferior lóbules semilunar) secundary (post-pyramidal) and the posterolateral (separating the nodule and the uvula and the hemisphere of lobe floculonodular), intraculminal and post-clival. Other less obvious fissures are the pré-central, pré-culminal and intra-biventer. The cuts to morfological internal analysis were effected according to the average and horizontal sagittal plans, with tickness from 2 to 3 mm, being colours by muligans solutions. The obvious structures are described with details comparing the data obtained with the researched literature. The anatomic terms were refered according to the Anatomic Terminology (International), first Brazilian edition- 2001, Ed. Manole Ltda.
