Exercise 2: The Effect of Weight on Finger Twitches.
1- Discuss how do the amplitudes of the finger twitches with different weights compare to each other?
2- Why did the amount of work decrease when heavier weights were used?
3- Is there any correlation between the weight moved and the contraction or relaxation times of the twitches?
Exercise 3: Stimulus-Response.
1- At which stimulus current did the finger first show a twitch? Why didn’t a finger twitch occur at a lower stimulus current?
2- How does the finger twitch amplitude increase when the stimulus current is increased?

2- How much greater than the amplitude of a single twitch is the amplitude of the tallest twitch during summation or incomplete tetanus?
3- How much greater than the amplitude of a single twitch is the amplitude of complete tetanus?
4- After the stimulator is turned off, the relaxation time after tetanus is much longer than relaxation time after a single twitch. Why?
