a) What are the THREE phases of a muscle twitch and what happens during each?

b) How do the three phases compare between the two muscles you have tested and why do they differ? (Two muscles tested were; one muscle has mostly Type IIx myofibers, while the other mostly has Type I myofibers)

c) If you were to stimulate both with a progressively higher voltage, what would happen to the twitch traces for either muscle (explain your reasoning briefly)?
