Question

Muscle X and Muscle Y are of same size but muscle X is capable of much finer control than muscle Y. Which of the following is most likely about muscle X?
A) It is controlled by much more neurons than muscle Y
B) It contains fewer motor units than muscle Y
C) It is controlled by fewer neurons than muscle Y
D) Each of its motor units consists of more cells than motor units of muscle Y

Answer 1

d ) Each of its motor units consists of more cells than motor units of muscle Y

Answer 2

The correct answer is option A

The Muscle X is controlled by much more neurons than muscle Y this is the reason the contraction and relaxation of muscle x is much more as that of muscle Y.

Suppose there are two muscle, one is controlled by less number of neurons and other one is controlled by more number of neurons. Then the muscle which is controlled by more neurons has better response.
