Question

Muscle A and muscle B have the same number of fibers, but muscle A is capable of more precise control than muscle B. Which of the following is likely to be true of muscle A? (Explain your answer.)
a. It is controlled by more neurons than muscle B.
b. It contains fewer motor units than muscle B.
c. It is controlled by fewer neurons than muscle B.
d. It has larger sarcomeres than muscle B.

Accepted Answer

Hello everyone and welcome to today's video. So which of the following contributes to the regulation of Mosul tension. As it turns out, the regulation of Mosul tension is going to be performed by the frequency of action potentials. As it turns out, these action potentials which are the signals they're going to be telling the muscle to either tense up or relax. If we have a very high frequency of action potentials, this is going to keep the Mosul tense. If we have a very low frequency of action potentials is going to lead the Mosul to be relaxed because of this, the correct answer choice is going to be answer choice. B action potential frequency is going to be the main regulator of muscle tension. I really hope this video helped you and I hope to see you on the next one.
