Muscles that produce precise,delicate movements have fewer muscle fibers in their motor units compared to muscles made for powerful movements.

Question

Muscles that produce precise,delicate movements have fewer muscle fibers in their motor units compared to muscles made for powerful movements.​

Quizplus · Accepted Answer

This is because precise, delicate movements require finer control, which can be achieved through fewer muscle fibers in their motor units. On the other hand, powerful movements require larger, stronger muscle contractions, which require more muscle fibers to be recruited.
