Vedclass · Answer

(C) The resting membrane potential of a neuron is maintained by the differential permeability of the membrane to ions. When a stimulus is applied to a site on the polarized membrane,the permeability of the membrane to $Na^+$ ions increases rapidly. This leads to a rapid influx of $Na^+$ ions into the intracellular space,which causes the reversal of the polarity at that site,a process known as depolarization. Therefore,the correct answer is $Sodium$ $(Na^+)$ ions.

The depolarization of nerve membrane takes place through influx of . . . . . . ions.
