The cerebellum is also known as “little brain”, it is composed of white matter and a thin, outer layer of densely folded gray matter. It contains hundreds of millions of neurons for processing data. It is also involved in the coordination of voluntary motor movement, balance, and equilibrium and muscle tone. The cerebellum is situated at the base of the skill, above the brain stem which is located toward the back of the brain. Injury to the cerebellum result in movement that is slow and uncoordinated.

The cerebellum relays information between body muscles and areas of the cerebral cortex that are involved in motor control.
Functions of the cerebellum involve:

  • Fine movement coordination
  • Balance and Equilibrium
  • Muscle tone

Cerebellum disorders
  • Ataxia - Incoordinationof movement, instability of gait, impairment of articulation,and difficulty with eye movement
  • Stroke or Multiple Sclerosis
  • Tumors- mass in cerebellum
  • Toxins such as ethanol, phenytoin, or chemotherapy.
