Protocol

In this experiment the sciatic nerve is stimulated electrically with different voltages. The isometric tension developed by the gastrocnemius muscle is recorded.

You should select different voltages by clicking on these buttons on the stimulator panel to increase or decrease the stimulus voltage.

Task
You should stimulate the nerve with different voltages and measure the peak amplitude of the muscle contraction at each stimulus voltage.

Tabulate your results and then try answering the questions.
