What is the function of cerebellum?

The cerebellum is responsible for maintaining balance and regulating muscle tone. When the cerebellum is diseased, the patient may show dizziness and unstable walking. If the cerebellar hemisphere is diseased, the patient may show left and right walking deviation and falling phenomenon. If the cerebellar vermis is diseased, the patient may show the performance of falling back and forth. Then, the cerebellum also has a certain regulatory effect on muscle tone. In general, patients with cerebellar lesions can also show changes in muscle tension. Secondly, cerebellum also has a certain impact on language. When cerebellum lesions occur, patients can show poetry-like language. For cerebellum, it is clinically more common in cerebellar infarction, but also seen in cerebellar hemorrhage. For cerebellar hemorrhage, if more than 15ml, surgery is recommended. In short, the role of cerebellum is mainly in charge of balance and regulation of muscle tension.
