  1. The biceps femoris is a member of which muscle group?

    Answer: Hamstrings

    The biceps femoris, along with the semitendinosus and semimembranosus, forms the hamstring muscle group at the posterior thigh.

  2. Which of the following best describes the role of the Golgi tendon organ (GTO)?

    Answer: Responds to muscle tension to inhibit contraction

    GTOs sense excessive muscle tension and trigger autogenic inhibition, causing the contracting muscle to relax as a protective mechanism.

  3. Which blood vessel carries deoxygenated blood from the right ventricle to the lungs?

    Answer: Pulmonary artery

    The pulmonary artery is the only artery in the body that carries deoxygenated blood, transporting it from the right ventricle to the lungs.

  4. Type II alveolar cells in the lungs produce which substance critical for normal breathing?

    Answer: Surfactant

    Type II pneumocytes secrete pulmonary surfactant, which reduces alveolar surface tension and prevents alveolar collapse.

  5. Which plane divides the body into anterior and posterior sections?

    Answer: Frontal (coronal) plane

    The frontal (coronal) plane divides the body into anterior (front) and posterior (back) portions.

  6. The primary fuel source for high-intensity, short-duration exercise lasting 10-30 seconds is:

    Answer: Phosphocreatine and glycolysis

    Short, intense efforts rely on the phosphagen system (ATP-PC) and rapid glycolysis to regenerate ATP quickly without oxygen.

  7. Which structure connects a muscle to bone?

    Answer: Tendon

    Tendons are dense connective tissue structures that transmit force from contracting muscles to the bones they move.
