Vedclass · Answer

(C) During the resting state,the axonal membrane is more permeable to $K^{+}$ ions and nearly impermeable to $Na^{+}$ ions. When a stimulus is applied at a site on the polarized membrane,the permeability to $Na^{+}$ ions increases rapidly. This leads to a rapid influx of $Na^{+}$ ions followed by the reversal of the polarity at that site,which is called depolarization. During this phase,the $Na^{+}$ voltage-gated channels open,while the $K^{+}$ voltage-gated channels remain closed.
