Questions and Answers
  • 1. 

    The capacity of a muscle cell to shorten forcefully is known as

    • A.

      Contractitlity

    • B.

      Excitability

    • C.

      Extensibility

    • D.

      Elasticity

    • E.

      Flexibility

    Correct Answer
    C. Extensibility
    Explanation
    The capacity of a muscle cell to shorten forcefully refers to its ability to contract, which is known as contractility. Extensibility, on the other hand, refers to the ability of a muscle cell to stretch or lengthen. Therefore, extensibility is not the correct answer for the given question.

    Rate this question:

  • 2. 

    Muscles exhibit the property of excitability.  This means that the muscle

    • A.

      Shortens its length

    • B.

      Recoils to its original resting length.

    • C.

      Stretches beyond its normal length.

    • D.

      Responds to stimulation by the nervous system.

    • E.

      Excites itself.

    Correct Answer
    D. Responds to stimulation by the nervous system.
    Explanation
    Muscles exhibit the property of excitability, which means that they respond to stimulation by the nervous system. This response can lead to muscle contraction or relaxation, depending on the specific stimulus. The other options, such as shortening, recoiling, or stretching, are not accurate descriptions of the property of excitability. Additionally, muscles do not excite themselves; they require external stimulation from the nervous system to initiate a response.

  • 3. 

    Identify the statement concerning general functional characteristics of muscle that is true.

    • A.

      Muscle tissue shortens forcefully but lengthens passively.

    • B.

      Muscle tissue shortens passively but lengthens forcefully.

    • C.

      Muscle tissue can get shorter, but can not get longer.

    • D.

      Muscle tissue can get longer, but can not get shorter.

    • E.

      None of the above statements are true.

    Correct Answer
    A. Muscle tissue shortens forcefully but lengthens passively.
    Explanation
    Muscle tissue shortens forcefully but lengthens passively because of the arrangement of the contractile proteins, actin, and myosin, within the muscle fibers. During muscle contraction, myosin heads attach to actin filaments and pull them closer together, causing the muscle to shorten. This is an active process that requires energy. On the other hand, when the muscle relaxes, the myosin heads detach from the actin filaments and the muscle lengthens passively due to the recoil of elastic elements within the muscle. This lengthening is a passive process and does not require energy expenditure.

  • 4. 

    Identify the statement concerning skeletal muscle that is true.

    • A.

      It comprises about 20% of the body's weight.

    • B.

      It propels urine through the urinary tract.

    • C.

      Its function is largely under involuntary control.

    • D.

      It is a kind of connective tissue.

    • E.

      It is responsible for locomotion.

    Correct Answer
    E. It is responsible for locomotion.
    Explanation
    The statement "It is responsible for locomotion" is true. Skeletal muscle is the type of muscle tissue that is attached to bones and is responsible for voluntary movements of the body, such as walking, running, and lifting objects. It works in coordination with the skeletal system to provide support and movement.

    Rate this question:

  • 5. 

    A cord or strap of dense tissue that connects a muscle to bone is called a:

    • A.

      Tendon

    • B.

      Ligament

    • C.

      Bursa

    • D.

      Arthiritis

    Correct Answer
    A. Tendon
    Explanation
    A cord or strap of dense tissue that connects a muscle to bone is called a tendon. Tendons are strong and flexible, allowing muscles to move bones and joints. They transmit the force generated by the muscle to the bone, allowing for movement and stability. Ligaments, on the other hand, connect bone to bone and help stabilize joints. Bursa is a fluid-filled sac that reduces friction between tendons and bones. Arthritis is a condition characterized by inflammation of the joints.
