Final answer:
Propagation along a myelinated axon is faster through saltatory conduction, as the action potential jumps from one node of Ranvier to the next. The myelination and the diameter of the axon affect the speed of conduction.
Step-by-step explanation:
Propagation along a myelinated axon is known as saltatory conduction, which is faster than continuous conduction along an unmyelinated axon. In saltatory conduction, the action potential jumps from one node of Ranvier to the next, while in continuous conduction, the action potential spreads along the entire length of the axon. The myelination and the diameter of the axon influence the speed of conduction, with wider axons allowing for faster propagation.
