Question
Below is a chart depicting the twitch of the lateral rectus eye muscle. As you can see, as time passes, there is an increase in the amount of tension in the muscle. For instance, from time 3 milliseconds to 4 milliseconds, the amount of tension increased from 10 kg-force to 20 kg-force.
Question: What happened to the muscle as tension increased during this time?
