Vedclass · Answer

(B) The resting membrane potential of a neuron is maintained by the selective permeability of the membrane to $K^+$ ions and the action of the $Na^+-K^+$ pump.When a stimulus is applied,the permeability of the axonal membrane to $Na^+$ ions increases significantly.This leads to a rapid influx of $Na^+$ ions into the axon.As a result,the inner side of the membrane becomes positively charged relative to the outer side,which is known as depolarization or the generation of an action potential.Therefore,the reversal of polarity occurs because more $Na^+$ ions enter the axon compared to $K^+$ ions.
