Lesson 8 Science Test Review

1. The brain is part of our nervous system.

2. Muscles are controlled by the nervous system.

3. Most tasks require the cooperation of different body parts.

4. People of the same age may NOT have the same reaction time.

5. Many things besides illegal drugs can impair a person’s reaction time.
