Q

How does the cerebellum function?

A
  • Coordinates motor activity (spinal and cranial nerves) and gives smootheness to movements initiated voluntarily in the cerebral cortex
  • Receives proprioceptive input from spinal cord, balance centers, cerebral cortex, visual cortex
  • Times muscular activity so that muscles contract at the right time smoothly
