MAIN FEATURES OF THE ANATOMY OF THE CENTRAL NERVOUS SYSTEM
CEREBELUM – 1
The cerebellum consists of numerous thin folds of nervous tissue, each called a folium (plural: folia). The folia are visible on the surface of the cerebellum and can also be identified in sections of the organ, as shown in the lower figure. Their boundaries are indicated by black lines in the upper figure and one folium is surrounded in red in the lower figure.
Distribution of gray and white matter within each folium
A central region of white matter, indicated by the arrow, connects each folium with the deeper white matter of the cerebellum. Extensions of this white matter penetrate into the folium and form its core.
Gray matter surrounds the white-matter core and forms the outer layer of each folium.
