Vedclass · Answer

(B) In a resting state,the axonal membrane is polarized,meaning the inside is negatively charged relative to the outside.When a stimulus is applied,the permeability of the membrane to $Na^+$ ions increases,causing an influx of $Na^+$.This leads to depolarization,where the inside of the membrane becomes positively charged.Following this,the membrane permeability to $K^+$ increases,and $K^+$ ions move out,leading to repolarization,where the membrane potential returns to its original negative state.

When a neuron is stimulated to generate a nerve impulse,the electrical potential on the inside of the nerve membrane changes:
