D)nature of the neural stimulation ONLY.

Question

Quizplus · Accepted Answer

The amount of force exerted during muscular contraction is dependent on multiple factors, including the type of motor units recruited, the initial length of the muscle, and the nature of the neural stimulation. Motor units are groups of muscle fibers innervated by a single motor neuron, and the type of motor unit recruited (e.g. slow-twitch or fast-twitch) can affect the force generated. The initial length of the muscle can also impact force, as muscles generate maximum force at a specific length. Finally, the nature of the neural stimulation (e.g. frequency and intensity of electrical impulses) can impact the number and type of motor units recruited and the force generated. Therefore, choice B is the best answer.
