Question

Quizplus · Accepted Answer

Myelination increases the speed of conduction of action potentials. This is because myelin sheaths insulate axons and allow for saltatory conduction, meaning that action potentials "jump" from one node of Ranvier to the next instead of traveling down the entire length of the axon. This allows for much faster conduction of the signal.
