The cerebellum is a large brain mass that is located at the very base of the brain in us, humans , it accounts for 10 – 15% of brain weight, 40% of the brain’s surface area and holds 50% of the brain’s neurons (nerve cells. The cerebellum is involved in the coordination of voluntary motor movement, balance and equilibrium and muscle tone it is located just above the brain stem and toward the back of the brain. In latin, the word cerebellum means little brain the cerebellum is the area of the hindbrain that controls movement coordination, balance, equilibrium and muscle tone like the cerebral cortex, the cerebellum is comprised of white matter and a thin, outer layer of densely folded gray matter. The cerebellum fine-tunes cognitive function like it fine-tunes muscle movement. Cerebellar syndrome is the term used to designate manifestations of damage to the cerebellum, regardless of origin for example, if a patient with cerebellar syndrome tries to touch an object, the movement of his hand will begin late, then accelerate beyond what is. Cerebellum, section of the brain that coordinates sensory input with muscular responses, located just below and behind the cerebral hemispheres and above the medulla oblongata. The cerebellum (latin for little brain) is a region of the brain that plays an important role in motor control it may also be involved in some cognitive functions such as attention and language, and in regulating fear and pleasure responses, but its movement-related functions are the most solidly established.
