The Cerebellum Coordinates Movement and Maintains Balance

The cerebellum coordinates movement and maintains balance.
It sits at the back of the brain, just below the cerebral hemispheres.
It is highly folded, which packs a large surface area into a compact space.

Definition

Cerebellum

The part of the brain responsible for coordinating voluntary muscle movements, balance, and motor control.

Analogy

The first time you ride a bike, every movement feels awkward.
With practice, your body learns to balance and pedal smoothly.
That smooth control comes largely from the cerebellum.

The Cerebellum Compares Sensory Input With Motor Commands

Sensory input tells the cerebellum where the body is.
1. Proprioceptors in muscles and joints signal body position and movement.
2. The vestibular system in the inner ear signals balance and spatial orientation.
