Answers and explanations

  1. Question: What body part helps you smile?
    Answer: Facial muscles
    Explanation: Facial muscles move your lips and cheeks to make a smile. People sometimes say the brain makes you smile, but muscles actually do the moving.
  2. Question: Which muscle helps you run fast?
    Answer: Quadriceps
    Explanation: The quadriceps are big front thigh muscles that push your legs forward when running. Many guess 'calves,' but calves help push off the ground, while quads power the leg lift.
  3. Question: What muscle do you use to lift your arm up?
    Answer: Deltoid
    Explanation: The deltoid sits on the shoulder and lifts the arm outward and up. Some might say 'biceps,' but biceps bend the elbow rather than lift the whole arm.
  4. Question: Which muscle helps you chew food?
    Answer: Masseter
    Explanation: The masseter is a strong jaw muscle used for chewing. People often guess 'tongue,' but the tongue moves food, while the masseter crushes it.
  5. Question: What type of muscle is the heart?
    Answer: Cardiac muscle
    Explanation: The heart is made of cardiac muscle that never stops working to pump blood. It is not the same as skeletal muscles used for moving arms or smooth muscles inside organs.
  6. Question: Which muscles help your tummy breathe in and out?
    Answer: Diaphragm
    Explanation: The diaphragm is a dome-shaped muscle under the lungs that moves down to let air in. Some think lungs do the breathing, but lungs need the diaphragm to change air pressure.
  7. Question: What are muscles made of that make them strong?
    Answer: Fibers
    Explanation: Muscles are bundles of tiny fibers that pull to make parts move. People might say 'fat' or 'bone,' but fibers are the real working pieces.
