What characteristic of fast nerve fibers permits them to transmit signals perceived as sharp, immediate pain?
A) They are nonmyelinated axons,which transmit signals faster than myelinated axons.
B) They tell your brain where your body is in space,so they allow you to perceive immediate pain.
C) They are myelinated axons,which transmit signals faster than nonmyelinated axons.
D) They respond to continued vibration and fast pressure,so they transmit pain more easily.
