When Comparing a Motor Nerve to a Sensory Nerve on a Strength

When comparing a motor nerve to a sensory nerve on a strength duration curve, how long would the pulse duration need to be to elicit a response from a motor nerve as compared to the duration needed to elicit a response from a sensory nerve?

A) Longer
B) Shorter
C) Both types of nerves have the same requirements for pulse duration.
D) The pulse duration is irrelevant if the amplitude is increased.
