Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentratio...
