Question

Quizplus · Accepted Answer

Myelin is a fatty substance that wraps around the axon of a neuron, serving as insulation that allows for faster transmission of electrical signals. Similarly, rubber is an insulating material used in wire insulation to prevent electrical currents from escaping and also allows for more efficient transmission of electrical signals. The other options (telephone, switchboard, poles, and jack) do not directly relate to the function of myelin in the same way that rubber wire insulation does.
