Question : 51.Fast-glycolytic muscle fibers do not require as much oxygen use : 1417095

51.Fast-glycolytic muscle fibers do not require as much oxygen use as slow-oxidative fibers.

52.Slow-oxidative muscle fibers would be found in high density in the leg muscles of Olympic sprinters.

53.A skeletal muscle undergoes hypertrophy mainly by producing many more muscle fibers.

54.Atrophy can develop in a muscle by either denervation or disuse.

55.Skeletal muscles are capable of limited repair after injury.

56.Single-unit smooth muscle has no innervation.

57.The lever system at the elbow joint provides a mechanical advantage so that when the biceps muscle contracts to flex the elbow joint and lift an object in the hand, the force developed in the biceps can be considerably less than the actual load that is moved.

58.The corticospinal system controls fine, discrete, voluntary body movements.

59.The two types of fast twitch fibers are interconvertible depending on the type of conditioning they receive.

60.Single-unit smooth muscle and cardiac muscle are both self-excitable.
