Students have asked these similar questions
If individual muscle fibers always contract the entire way when stimulated, how are we able to create precise and delicate movements with our bodies?
Why will an increase in the strength of a stimulus cause an increase in the force of contraction in a whole muscle but not in a single muscle fiber?
Name three differences between slow-twitch and fast-twitch muscle fibers.
