Question

Quizplus · Accepted Answer

The cerebellum is responsible for fine motor coordination and balance, so damage to this area would likely result in difficulty with tasks such as using a pencil or threading a needle. The hippocampus is involved in memory processing, the medulla controls basic life-sustaining functions like breathing and heartbeat, and the reticular activating system helps regulate arousal and attention, but none of these areas would directly impact motor coordination and dexterity.
