  • 2. 

    Which fiber type has more myoglobin?

    • Intermediate fibers

    • White fibers

    • Red fibers

    • None of the above

    Correct Answer
    A. Red fibers
    Explanation
    Skeletal muscle fibers can be classified as red fibers, white fibers or intermediate fibers. Red fibers are smaller in diameter; white fibers are larger in diameter. Red fibers have more mitochondria than white fibers. Red fibers make up slow-twitch muscle; white fibers make up fast-twitch muscle. Red fibers are more resistant to fatigue than are white fibers. Red fibers have more myoglobin (oxygen binding pigment) than white fibers. White fibers store glycogen and use anaerobic metabolism.

    Red fiber and slow twitch muscle is for endurance.

    White fiber and fast twitch muscle is for a burst of power.

    Which of the following is composed of smooth muscle?

    • Upper esophagus

    • Heart

    • Tongue

    • Walls of the visceral organs

    Correct Answer
    A. Walls of the visceral organs
    Explanation
    There are two chief categories of muscle: striated and non-striated muscle (smooth muscle). Striated muscle can be sub-categorized into cardiac muscle and skeletal muscle. The tongue, biceps muscle, and upper esophagus are made of striated muscle. The heart is composed of cardiac muscle. Nonstriated muscle is also called smooth muscle. Smooth muscle is involuntary muscle. It is found in viscera and blood vessels.

    What is the cytoplasm of a muscle cell?

    • Epimysium

    • Sarcolemma

    • Sarcoplasm

    • Perimysium

    Correct Answer
    A. Sarcoplasm
    Explanation
    The outer connective tissue covering of a muscle is the epimysium. Within the muscle, there are subdivisions called fascicles. The perimysium surrounds these muscle fascicles. The endomysium is the covering around an individual muscle fiber. The sarcolemma is the plasma membrane of a muscle cell. The sarcoplasm is the cytoplasm of a muscle cell.

    What type of muscle contains centrally placed nuclei?

    • Smooth muscle

    • Cardiac muscle

    • Both Cardiac muscle &Smooth muscle

    • Skeletal muscle

    Correct Answer
    A. Both Cardiac muscle &Smooth muscle
    Explanation
    Skeletal muscle fibers are multinucleated. The nuclei are located on the periphery of the cell. In cardiac muscle, the nucleus is located centrally. In smooth muscle, there is also a centrally placed nucleus.

    PEARL from Sarah Bellham: This is an important point, as both skeletal muscle and cardiac muscle are striated. The centrally placed nucleus seen in cardiac muscle is one of the things that can be used to distinguish between the two.

    What are the bundle of longitudinal contractile elements within a muscle cell called?

    • Myofilaments

    • Myocardium

    • Myofibrils

    • Myosin

    Correct Answer
    A. Myofibrils
    Explanation
    Myofilaments are the contractile protein within a muscle cell. The myofilaments are actin and myosin. The thin filaments are actin and the thick filaments are myosin. The muscle cell is a muscle fiber. The term "muscle cell" and "muscle fiber" are synonymous. A myofibril is a longitudinal bundle of myofilaments within a muscle cell. Myocardium is the muscular layer of the heart. Thus, the myocardium is composed of cardiac muscle.
