Which part of the brain controls balance and movement accuracy?

  • Cerebrum
  • Cerebellum
  • Thalamus
  • Medulla oblongata
Correct Answer: B. Cerebellum

Detailed Explanation

The cerebellum is the part of the brain that controls balance and precise movements. It is located at the back of the head, under the cerebrum.


The cerebellum helps in:




  • Keeping the body balanced when standing, walking, or running




  • Making movements smooth and accurate, like writing, playing sports, or picking up objects




  • Adjusting the body automatically for proper posture




Other brain parts have different jobs:




  • Cerebrum handles thinking, memory, and voluntary movements




  • Thalamus acts as a relay station for sensory signals




  • Medulla oblongata controls involuntary actions like heartbeat and breathing




The cerebellum works by receiving information from muscles, joints, and the inner ear, then coordinating movements so they are correct and balanced. If the cerebellum is damaged, it can cause clumsiness, poor balance, and tremors.
