D) nature of the neural stimulation only.

Question

Quizplus · Accepted Answer

The amount of force exerted during muscular contraction is dependent on the type of motor units recruited, the initial length of the muscle, and the nature of the neural stimulation. The type of motor units recruited refers to the size and firing threshold of the motor units activated, which will affect the force generated. The initial length of the muscle also affects the force generated, as muscles have an optimal length at which they generate the greatest force. Lastly, the nature of the neural stimulation, such as the frequency and duration of the action potential, will influence the force produced by the muscle.
