The cerebellum regulates the balance of the body through the lobule of villi, namely the cerebellum. The balance adjustment of the body is a reflex process, and villous lobules are the central device of this reflex activity.

2. Adjust muscle tension:

Muscle tension is the basic reflex activity of muscle fiber group contraction in rotation, which makes the whole muscle in a state of frequent mild contraction, thus maintaining the standing posture of the body. Cerebellum can regulate muscle tone activity, and its regulation function is manifested in two aspects: inhibiting muscle tone and promoting muscle tone.

3. Coordinate independent movements:

Voluntary movement is a conscious movement initiated by the cerebral cortex, and the coordination of voluntary movement is completed by the hemispheric part of the cerebellum, that is, the neocerebellum. The injury of the new cerebellum will lead to the decrease of muscle tone and interfere with the coordination of voluntary movement, that is, cerebellar ataxia.
