What relationship exists between the number of muscle fibers in a motor unit and the rate and accuracy of muscle contraction?
a) The greater the number of muscle fibers, the slower and less accurate the contraction.
b) The fewer the number of muscle fibers, the slower and less accurate the contraction.
c) The greater the number of muscle fibers, the faster and more accurate the contraction.
d) The fewer the number of muscle fibers, the faster and more accurate the contraction.
e) There is no relationship between the number of muscle fibers and contraction speed or accuracy.
