Vedclass · Answer

(B) 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 from the extracellular fluid into the intracellular fluid,causing a reversal of polarity at that site,which is known as depolarization or the action potential. Therefore,the action potential results from the movement of $Na^+$ from the extracellular fluid into the intracellular fluid.

During the propagation of a nerve impulse,the action potential results from the movement of which of the following?
