(A) During the depolarization phase of an action potential,the voltage-gated $Na^+$ channels open rapidly,leading to a massive influx of $Na^+$ ions into the neuron. This causes the membrane permeability for $Na^+$ to increase significantly,far exceeding that of $K^+$. Therefore,$Na^+$ has the highest permeability during the generation of the nerve impulse.
