Physiology Saltatory conduction in myelinated axons results from the fact that: A Salt concentration is increased beneath the myelin segments B Nongated ion channels are present beneath the segments of myelin C Membrane resistance is decreased beneath the segments of myelin D Voltage-gated sodium channels are concentrated at the nodes of Ranvier π‘ Explanation Saltatory conduction in myelinated axons results from the fact that: β Correct Answer: D. Voltage-gated sodium channels are concentrated at the nodes of Ranvier
