Damage to the cerebellum would most likely result in
Correct answer: C. loss of balance and jerky, poorly coordinated movement
- A. loss of memory
- B. failure of breathing
- C. loss of balance and jerky, poorly coordinated movement
- D. inability to see
Explanation
The cerebellum receives information from the muscles, joints and balance organs of the ear and smooths the commands sent by the cerebrum, so injury to it leaves movement clumsy and unsteady even though strength is normal. Alcohol depresses the cerebellum, which is why an intoxicated person staggers. Breathing is controlled by the medulla and vision is processed in the occipital lobe of the cerebrum.

About Brain
The brain includes the cerebrum, cerebellum, brainstem, hypothalamus and medulla, each with distinct roles in sensation, movement and homeostasis. Questions connect major brain regions with their functions, reflex control and coordination, while distinguishing involuntary responses from hormonal regulation.
