Question

Quizplus · Accepted Answer

Myelin performs a similar function to the plastic insulation on electrical wires in that it provides insulation for the axons of neurons, allowing for efficient transmission of electrical signals. The other options listed (neurotransmitters, nodes of Ranvier, and vesicles) do not provide insulation for the axons.
