    • A. 

      True

    • B. 

      False

  • 7. 
    What would happen if your body did not have neurotransmitters?
    • A. 

      Your nerve cells could not communicate with one another.

    • B. 

      Impulses could not travel along your nerve cells.

    • C. 

      You would not be able to touch the objects that surround you.

    • D. 

      Your nerve cells would begin dying off.

  • 8. 
    How are neurotransmitters different from the impulses that travel along the bodies of nerve cells?
    • A. 

      The impulses are electrical; neurotransmitters are chemical

    • B. 

      The impulses travel at a faster rate than neurotransmitters

    • C. 

      The impulses send signals from the body to the brain; neurotransmitters send signals from the brain to the body

    • D. 

      The impulses occur constantly; neurotransmitters are released only occasionally
