Answers and explanations

  1. Question: What is the tissue that makes your body move called?
    Answer: Muscle
    Explanation: Muscle tissue contracts to produce force and movement in the body; skeletal muscles pull on bones to enable voluntary actions like walking, while cardiac and smooth muscles power the heart and internal organs. Muscles are important because they convert chemical energy into mechanical work and play a
  2. Question: Which of the following helps you smile: bone, muscle, or skin?
    Answer: Muscle
    Explanation: Smiling is produced by facial muscles—especially the zygomaticus major—which pull the corners of the mouth upward. Fun fact: a genuine “Duchenne smile” also engages the orbicularis oculi around the eyes, making smiles more sincere and recognizable.
  3. Question: Why do muscles get bigger when you exercise?
    Answer: Muscle hypertrophy
    Explanation: Resistance exercise causes microscopic damage to muscle fibers, triggering repair and growth processes that add contractile proteins and increase fiber size — this is called muscle hypertrophy. Fun fact: growth is driven by mechanical tension, metabolic stress, and muscle damage, and adequate rest +
  4. Question: Who first studied how muscles work in old science books?
    Answer: Galileo Galilei
    Explanation: Galileo was among the earliest scientists to analyze muscle mechanics and motion using experiments and mathematics, laying foundations for biomechanics; his work helped shift studies of the body from philosophical speculation to empirical measurement. Fun fact: Galileo’s investigations into motion,杢
  5. Question: What is the strong band that attaches muscle to bone called?
    Answer: Tendon
    Explanation: A tendon is a tough band of fibrous connective tissue that connects muscle to bone, transmitting the force needed for movement. Interesting fact: tendons are mostly made of collagen and can withstand high tensile stress, but they have limited blood supply which makes healing slow.
  6. Question: Which muscle type moves your heart without you thinking?
    Answer: Cardiac muscle
    Explanation: Cardiac muscle (myocardium) contracts rhythmically and automatically to pump blood through the body without conscious control; its specialized pacemaker cells generate electrical impulses that coordinate each heartbeat. An interesting fact: cardiac muscle cells are branched and connected by intercal
  7. Question: How do muscles help you stand up from a chair?
    Answer: By contracting and extending
    Explanation: Muscles like the quadriceps and gluteals contract to straighten your knees and hips while opposing muscles lengthen to allow movement; this coordinated contraction and relaxation produces the force and joint motion needed to rise. Fun fact: standing up engages many muscles at once and is often used—
  8. Question: Which famous cartoon hero is known for very big muscles?
    Answer: Popeye
    Explanation: Popeye the Sailor is famous for his oversized forearm muscles, which he amplifies by eating spinach — a cartoon gag that popularized spinach as a symbol of strength and boosted its consumption in the 20th century.
