Vedclass · Answer

(A) The conduction of a nerve impulse is primarily driven by changes in the permeability of the axonal membrane to specific ions.When a stimulus is applied,the membrane permeability to $Na^+$ ions increases significantly,leading to an influx of $Na^+$ into the cell (depolarization).Subsequently,the permeability to $K^+$ ions increases,allowing $K^+$ to flow out of the cell (repolarization).These rapid changes in membrane permeability create the action potential necessary for impulse conduction.

The potential difference in the membrane,which is responsible for the conduction of an impulse,is brought about by a change in the membrane:
