cerebellum vermis lobule VII cerebellum vermis lobule VIIA The folium vermis is a short, narrow, concealed band at the posterior extremity of the vermis, consisting apparently of a single folium, but in reality marked on its upper and under surfaces by secondary fissures. Laterally, it expands in either hemisphere into a considerable lobule, the superior semilunar lobule (lobulus semilunaris superior; postero-superior lobules), which occupies the posterior third of the upper surface of the hemisphere, and is bounded below by the horizontal sulcus. The superior semilunar lobules and the folium vermis form the lobus semilunaris. folium of vermis of cerebellum folium lobule EMAPA:37823 vermic lobule VIIA UBERON:0005345 neuronames:675 neuraxis folium folium NLXANAT:20081231 FMA:83889 folium of cerebellum
