Which statement BEST describes the role of the Nodes of Ranvier in saltatory conduction?
They insulate the axon, preventing ion leakage.
They synthesize neurotransmitters for synaptic transmission.
They allow for faster action potential propagation by concentrating voltage-gated channels.
They slow down action potential propagation, allowing for greater control.
