O cerebellum is a part of the brain, therefore, it is part of what we call yesstem nograssy çentrance. It corresponds to one-tenth of the brain volume and occupies a large part of the posterior cranial fossa. It is divided into three lobes: anterior, posterior and flocculonodular.
It plays an important role in our body, acting, for example, in movement, balance, posture and muscle tone. Cerebellar lesions can therefore compromise the individual's balance, muscle tone and motor coordination.

What is the cerebellum?
the cerebellum is a part of brainwhich represents approximately one-tenth of the brain volume. The word cerebellum comes from the Latin, cerebellum, and means “small brain”. The cerebellum occupies most of the posterior cranial fossa and posterior to the bulb and bridge.
It is a structure of the central nervous system and presents the oval shape, with a constriction in the central region and expanded lateral portions. get the name of
The cerebellum divides into three wolves:
They are determined by the presence of deep cracks. The anterior and posterior lobes are related to the movement function, while the flocculonodular lobe is related to the balance function.
Functions of the cerebellum
The cerebellum is mainly known for its role in motor activities. When it is removed, body movements become abnormal, and although it does not cause paralysis of muscles, the coordination of fast muscular activities, such as running, may simply disappear. In addition to relating to movement, the cerebellum acts on balance, posture, muscle tone and it also helps us learn and remember motor skills.
The structure presents the incredible ability to compare real movements with movements programmed by the motor system. In this way, if he concludes that there is a difference between the two, corrective signals are transmitted in order to adjust the body's motor activities. In addition, the cerebellum also assists the cerebral cortex in planning the next sequential movement, ensuring progression from one movement to another.

cerebellar lesions can be quite dangerous and directly affect the balance, muscle tone and motor coordination of the individual. It can be injured due to problems such as cerebellar stroke, cerebellar diseases and syndromes, and traumatic brain injury.
