Which of the following statements concerning the rate of action potential propagation is TRUE?
A) It is faster in small-diameter axons than in large-diameter axons.
B) It is faster for a strong stimulus than for a weak one.
C) It is faster in myelinated axons than in nonmyelinated axons.
D) It is faster in the dendrites than in the axon.
E) It occurs at the same rate in all axons, regardless of their diameter.

Quizplus · Accepted Answer

Myelination of axons allows for saltatory conduction, meaning the action potential "jumps" from node to node instead of having to travel the entire length of the axon. This accelerates the rate of propagation in myelinated axons compared to nonmyelinated axons.
