What separates the two cerebral hemispheres? Longitudinal fissure
What separates the cerebrum from the cerebellum? Transverse fissure
What is the difference between fissures and sulci? Fissures are deep depressions, while sulci are shallow depressions in the
cerebrum
What are gyri? Elevated ridges or bumps of the cerebral cortex
What are the ventricles of the brain? Two lateral ventricles, the 3rd ventricle, and the 4th ventricle
