Which part of human brain is involved in maintaining the posture and balance of the body?
- A. Cerebrum
- B. Cerebellum
- C. Hypothalamus
- D. Medulla oblongata
Explanation
The cerebellum receives information from muscles, joints and the balance organs of the inner ear and smooths the commands issued by the cerebrum, so damage to it leaves movement clumsy and unsteady even though strength is normal. Alcohol depresses it, which is why an intoxicated person staggers. The medulla controls heart rate and breathing instead.
