Solution
The major function of the cerebellum is to analyze errors between intended motor output and actual motor output. The cerebellum plays a crucial role in motor control and it also contributes to cognitive functions. It receives information from the sensory systems and from other parts of the brain, and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
