Increasing the voltage of single shocks applied to the muscle produced contractions that increased in magnitude. Explain this observation in terms of threshold and the recruitment of additional muscle fibers into the response.

After opening the Ph.I.L.S. program, do Stimulus-Dependent Force Generation. Read the Objectives & Introduction and do all the activities. If you click on the underlined words in the Wet Lab, you will see video footage of the actual experiment.
Write a report on this in the required format. Do not cut and paste any portion of this exercise. Write an original report.
In the Conclusion section, please include responses to the following questions. Do not answer them as free standing questions, but incorporate them.

1. Low voltage electrical shocks produced no muscle tension. Why?
2. Increasing the voltage of single shocks applied to the muscle produced contractions that increased in magnitude. Explain this observation in terms of threshold and the recruitment of additional muscle fibers into the response.
3. High voltage electrical shocks produced maximum tension – i.e. further increases in shock voltage produced little change in tension. Explain this observation.
