The cerebrum and cerebellum are separated by the tentorium cerebelli or cerebellar tentorium, according to anatomyEXPERT. The tentorium is one of two special folds in the meningeal dura mater. The second is the falx cerebri, which separates the right and left hemispheres of the cerebrum, according to Mayfield Clinic.
The cerebrum is the largest part of the brain and is composed of right and left hemispheres. As explained by Mayfield Clinic, the cerebrum performs higher functions like touch, vision, hearing, speech, reason, emotions, learning and fine motor control. The cerebellum is located under the distal portion of the cerebrum and has the primary function of coordinating muscle movement and maintaining posture and balance.
