Vedclass · Answer

(A) During the transmission of a nerve impulse (depolarization),the permeability of the axonal membrane to $Na^+$ ions increases significantly.This leads to a rapid influx of $Na^+$ ions into the intracellular space.Simultaneously,the permeability to $K^+$ ions decreases,but as the action potential progresses toward repolarization,$K^+$ ions flow out of the cell.Therefore,the primary event during the initiation of the impulse is the inward flux of $Na^+$ and the outward flux of $K^+$.
