How does the contraction time of a typical finger twitch compare to the relaxation time?
Exercise 2: The Effect of Weight on Finger Twitches.Questions: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.Questions: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?3- Is there a stimulus current at which the amplitude of the finger twitch is maximized?4- Above a certain stimulus current, the amplitude of the finger twitch no longer increases. Why does this happen?
Exercise 4: Summation and Tetanus.Questions:1- At which frequency did summation first appear? At which frequencies does incomplete tetanus occur? At which frequency did complete tetanus first occur?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?5- What is the name for the decrease in the level of constant tension that occurs during tetanus?
