Which of the following is NOT a determinant of whole-muscle tension?
A)The number of muscle fibers contracting
B)The tension produced by each contracting fiber
C)The numbers of motor units recruited
D)The frequency of motor neuron stimulation
E)The proportion of the muscle fibers within each motor unit that are contracting at any given time

Question

Quizplus · Accepted Answer

While the proportion of the muscle fibers within each motor unit that are contracting at any given time can affect the smoothness and precision of muscle movements, it is not a determinant of whole-muscle tension, which is the force generated by the overall muscle contraction. The determinants of whole-muscle tension are A) the number of muscle fibers contracting, B) the tension produced by each contracting fiber, C) the numbers of motor units recruited, and D) the frequency of motor neuron stimulation.
