    _____________________________ carry oxygen to the muscles. 

    • A.

      White blood cells

    • B.

      Plateletes

    • C.

      Red blood cells

    • D.

      Fat cells

    Correct Answer
    C. Red blood cells
    Explanation
    Red blood cells carry oxygen to the muscles. They contain a protein called hemoglobin, which binds to oxygen in the lungs and transports it to the body's tissues. This process is crucial for delivering oxygen to the muscles, where it is needed for energy production during physical activity. White blood cells are responsible for fighting infections, platelets help in blood clotting, and fat cells store energy. However, neither of them have a direct role in carrying oxygen to the muscles.

    • D.

      Gastrocnemius

    Correct Answer
    B. Gluteus Maximus
    Explanation
    The gluteus maximus is the correct answer because it is the specific muscle group that is responsible for the shape and function of the buttocks. It is the largest muscle in the body and plays a crucial role in activities such as walking, running, and climbing stairs.

    Rate this question:

  • 6. 

     Muscle turn to fat or fat can  turn to muscle.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Muscle cannot turn into fat and fat cannot turn into muscle. These are two different types of tissues with different structures and functions. Muscle tissue is dense and fibrous, while fat tissue is soft and adipose. When a person stops exercising and loses muscle mass, it may appear as if their muscles have turned into fat because the muscle definition is lost and fat may accumulate. Similarly, when a person starts exercising and gains muscle, it may appear as if their fat has turned into muscle because the fat is being replaced by muscle tissue. However, these are separate processes and one cannot physically transform into the other.

    Rate this question:

  • 7. 

    You can add or subtract muscle or fat cells.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    It is not possible to add or subtract muscle or fat cells. Muscle and fat cells can increase or decrease in size, but the number of cells remains relatively constant throughout adulthood. This means that you cannot physically add or remove muscle or fat cells from your body.

    Rate this question:

  • 8. 

    Muscles shorten when they contract. 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Muscles shorten when they contract because the actin and myosin filaments within the muscle fibers slide past each other, causing the muscle to contract and become shorter in length. This is known as the sliding filament theory of muscle contraction.

    Rate this question:

  • 9. 

    Involuntary muscles have smooth muscle fiber.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Involuntary muscles, also known as smooth muscles, are found in various organs of the body such as the digestive system, blood vessels, and respiratory system. These muscles are not under conscious control and their contractions are involuntary. Smooth muscles are characterized by their smooth appearance under a microscope, hence the name. Therefore, the statement that involuntary muscles have smooth muscle fibers is correct.

    Rate this question:

  • 10. 

     Involuntary muscles have striated muscle fiber.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Involuntary muscles, such as the muscles found in the walls of internal organs like the stomach and intestines, do not have striated muscle fibers. Striated muscle fibers are found in voluntary muscles, which are responsible for conscious movements of the body, like the muscles in our arms and legs. Involuntary muscles, on the other hand, are not under our conscious control and therefore do not have striated muscle fibers.

    Rate this question:

  • 11. 

    You can control striated muscle fiber. 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Striated muscle fibers are under voluntary control, meaning that an individual can consciously control their contraction and relaxation. This is in contrast to smooth muscle fibers, which are involuntary and not under conscious control. Therefore, the statement that you can control striated muscle fibers is true.

    Rate this question:

  • 12. 

    You can control smooth muscle fiber. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Smooth muscle fibers are involuntary muscles, meaning they are not under conscious control. They are found in the walls of organs and blood vessels and are responsible for various involuntary movements, such as peristalsis in the digestive system. Therefore, the statement that you can control smooth muscle fibers is false.

    Rate this question:

  • 13. 

    Muscles have the ability to contract not extend. 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Muscles have the ability to contract, which means they can shorten and generate force. This is how muscles produce movement in the body. However, muscles do not have the ability to extend on their own. While they can relax and return to their original length, the act of extending a muscle requires the action of an opposing muscle or an external force. Therefore, the statement that muscles have the ability to contract but not extend is true.

    Rate this question:

  • 14. 

    Fat cells lay on top of the muscle and shrink with exercise. 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Fat cells are located on top of the muscle tissue in the body. When we exercise, our muscles contract and burn calories, causing the fat cells to shrink. This is why regular exercise is often recommended for weight loss and reducing body fat. Therefore, the statement "Fat cells lay on top of the muscle and shrink with exercise" is true.

    Rate this question:

  • 15. 

    Your bicep is located in your leg. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is false. The bicep is a muscle located in the upper arm, not in the leg.

    Rate this question:

  • 16. 

    The heart is an example of cardiac muscle.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The heart is indeed an example of cardiac muscle. Cardiac muscle is a specialized type of muscle found only in the heart. It is responsible for the contraction and relaxation of the heart, allowing it to pump blood throughout the body. Unlike skeletal muscle, which can be consciously controlled, cardiac muscle works involuntarily, meaning it contracts and relaxes without conscious effort. This unique muscle type is essential for the proper functioning of the heart and the circulatory system.

    Rate this question:

  • 17. 

     You CANNOT control voluntary muscles.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is incorrect. You can control voluntary muscles. Voluntary muscles are the ones that we can consciously control, such as the muscles in our arms and legs. We can choose to move them or not.

    Rate this question:

  • 18. 

    The three basic types of muscle are voluntary, involuntary and cardiac.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because there are indeed three basic types of muscle: voluntary, involuntary, and cardiac. Voluntary muscles are under conscious control, allowing us to move our limbs and perform actions. Involuntary muscles, on the other hand, are not under conscious control and are responsible for functions such as digestion and breathing. Cardiac muscles are a specialized type of involuntary muscle found only in the heart, enabling it to contract and pump blood. Therefore, the statement accurately describes the three basic types of muscle.

    Rate this question:

  • 19. 

    Red muscle fibers represent speed, fast, sprinter type. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because red muscle fibers actually represent endurance and slow-twitch muscle fibers. These fibers are more resistant to fatigue and are used for activities that require sustained effort over a long period of time, such as long-distance running or cycling. On the other hand, white muscle fibers are responsible for speed and power and are used for activities that require quick and explosive movements, such as sprinting or weightlifting.

    Rate this question:

  • 20. 

    White muscle fiber represents strong, slow, weightlifter type. 

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    White muscle fiber actually represents fast-twitch muscle fibers, which are responsible for generating short bursts of strength and power. These fibers are commonly found in athletes who require quick and explosive movements, such as sprinters or jumpers. In contrast, red muscle fibers are slow-twitch fibers that are more fatigue-resistant and are typically found in endurance athletes like long-distance runners. Therefore, the given statement is false.
