What are some physical effects of alcohol on the nervous system?

• A. Brain activity speeds up, coordination improves, reflexes sharpen.
• B. No change in brain function.
• C. Brain activity slows down, coordination becomes impaired, and reflexes sluggish.
• D. Alcohol causes immediate permanent brain damage.

Answer: (C)

Alcohol acts as a central nervous system depressant, so it slows how the brain processes information. This dampened brain activity affects areas that control thinking, judgment, and coordination. That slowing makes reaction times longer, balance harder to maintain, and movements feel less precise, which is why reflexes appear sluggish. In contrast, alcohol does not speeds up brain activity or improve coordination, so the option describing faster thinking and better reflexes isn’t accurate. There’s also no immediate permanence to brain damage from typical drinking episodes, though long-term heavy use can cause lasting brain changes.
