The question asks:
What is the closest distance the electrodes used in an NCV test can be placed in a nerve in order to measure the voltage change as a response to the stimulus?
a. .01m
b. .1m
c. 1m
d. 10m
The answer key states that you somehow know the action potential time response is 1 msec...where did this come from? It says figure 1 shows this but figure 1 is just a circuit diagram. I get that once you know the time you can just multiple the speed x time to get the distance but I don't get where the time 1 msec came from.
Can anybody help shed some light? I have a feeling there's something really obvious in the passage I'm just missing.
