Vedclass · Answer

(B) When a stimulus is applied to a nerve fiber,the membrane potential changes. Depolarization occurs due to the rapid influx of $Na^+$ ions into the axoplasm through voltage-gated $Na^+$ channels. This sudden increase in the permeability of the membrane to $Na^+$ ions causes the inside of the membrane to become positively charged relative to the outside,leading to the generation of an action potential.

During the depolarization of the nerve membrane,the nerve behavior is characterized by:
