WebAt the nodes of Ranvier region of the axon, sodiun enters the axon via a Na channel changing the charge in the area of the axon at the Na channel to more positive. This movement of sodium ions across the Na channel depolarizes the axon. Depolarization is not dependent on the movement of anions on the inside of the axon "away from the … WebCorrect option is D) Node of Ranvier are the periodic gaps present in the form of narrow areas in the insulating myelin sheath on the axon of a neuron. At the nodes of Ranvier the cell membrane is exposed i.e is non-myelinated. It has channel proteins that allow ions to enter and exit the cell bringing about the rapid conduction of nerve impulses. power bi change filter with button
