Definition (MEDLINEPLUS)

When you play the piano or hit a tennis ball you are activating the cerebellum. The cerebellum is the area of the brain that controls coordination and balance. Problems with the cerebellum include

  • Cancer
  • Genetic disorders
  • Ataxias - failure of muscle control in the arms and legs that result in movement disorders
  • Degeneration - disorders caused by brain cells decreasing in size or wasting away

Treatment of cerebellar disorders depends on the cause.

NIH: National Institute of Neurological Disorders and Stroke

Definition (MSH) Diseases that affect the structure or function of the cerebellum. Cardinal manifestations of cerebellar dysfunction include dysmetria, GAIT ATAXIA, and MUSCLE HYPOTONIA.
Definition (CSP) condition in which there is a deviation from or interruption of the normal structure or function of the cerebellum; manifestations of cerebellar dysfunction include dysmetria, gait ataxia, and muscle hypotonia.

Ontology: Cerebellum (C0007765)

Definition (FMA) Segment of neuraxis that has as its parts the cerebellar cortex, cerebellar nuclear complex and cerebellar white matter. Examples: There is only one cerebellum.
Definition (NCI_CDISC) The portion of the brain located at the base of the skull that is responsible for balance, equilibrium and movement. (NCI)
Definition (NCI) The portion of the brain located at the base of the skull that is responsible for balance, equilibrium and movement.
Definition (NCI_NCI-GLOSS) The portion of the brain in the back of the head between the cerebrum and the brain stem. The cerebellum controls balance for walking and standing, and other complex motor functions.
Definition (CSP) part of the metencephalon that lies in the posterior cranial fossa behind the brain stem; it is involved in the coordination of movement.
Definition (MSH) The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.
