cerebellum

 [ser″ĕ-bel´um]
the part of the metencephalon situated on the back of the brainstem, to which it is attached by three peduncles on each side (the cerebellar peduncles); it consists of a median lobe (vermis) and two lateral lobes (the cerebellar hemispheres). See also brain.

cer·e·bel·lum

, pl.

ce·re·bel·la

(ser'e-bel'ŭm, -bel'ă), [TA]
The large posterior brain mass lying posterior (dorsal) to the pons and medulla and inferior to the tentorium cerebelli and posterior portion of the cerebrum; it consists of two lateral hemispheres united by a narrow middle portion, the vermis.
[L. dim. of cerebrum, brain]

cerebellum

(sĕr′ə-bĕl′əm)
n. pl. cere·bellums or cere·bella (-bĕl′ə)
The trilobed structure of the brain, lying posterior to the pons and medulla oblongata and inferior to the occipital lobes of the cerebral hemispheres, that is responsible for the regulation and coordination of complex voluntary muscular movement as well as the maintenance of posture and balance.

cer′e·bel′lar (-bĕl′ər) adj.

cer·e·bel·lum

, pl. cerebella, pl. cerebellums (serĕ-belŭm, -ă, -ŭmz) [TA]
The large posterior brain mass lying dorsal to the pons and medulla and ventral to the posterior portion of the cerebrum; it consists of two lateral hemispheres united by a narrow middle portion, the vermis.

cerebellum

The smaller sub-brain lying below and behind the CEREBRUM. The cerebellum has long been thought to be concerned only with the coordination of information concerned with posture, balance and fine voluntary movement. Recent studies have shown, however, that the cerebellum functions to assist in many cognitive and perceptual processes. The cerebellum may also have a role to play in coordinating sensory input, and even in memory, attention and emotion.

cerebellum

the anterior dorsal (and largest) part of the HINDBRAIN which controls balance, muscle tone and the coordination of voluntary muscle. It is best developed in birds and mammals; in the latter there is a cortex of grey matter and the surface is complexly folded. The folds are lined with PURKINJE CELLS. Removal of the cerebellum unbalances an animal and affects the accuracy of voluntary movements such as walking, swimming, knitting.

Cerebellum

The part of the brain involved in coordination of movement, walking, and balance.

cer·e·bel·lum

, pl. cerebella, pl. cerebellums (serĕ-belŭm, -ă, -ŭmz) [TA]
The large posterior brain mass lying dorsal to the pons and medulla and ventral to the posterior portion of the cerebrum; it consists of two lateral hemispheres united by a narrow middle portion, the vermis.

Patient discussion about cerebellum

Q. can you recover after a cerebellar stroke?

A. You can recover after a cerebellar stroke but the process takes time and rehabilitation. With the right kind of rehab people reach great results, supposing of course the initial injury allows it.

Q. Is there any problem, if an arachnoid cyst ,2cmx1.5cm size, rostral to cerebellar region left untreated? symptoms: repeated headaches, twitching of muscles, tiredness

A. An arachnoid cyst that leads to symptoms usually needs treatment. Mild symptoms as you suggested are ok to left untreated however gradual onset of new symptoms may arise such as seizures, paralysis and other complications, therefore once symptoms occur one should consider treatment.
