Vedclass · Answer

(B) In a resting state,the axonal membrane is polarized,meaning the inside is negative relative to the outside. When a stimulus is applied,the membrane becomes permeable to $Na^+$ ions,causing depolarization where the inside becomes positive. This is followed by repolarization,where the membrane becomes permeable to $K^+$ ions,causing the inside to return to its original negative state. Therefore,the charge changes from negative to positive and back to negative.

During the transmission of a nerve impulse,the potential inside the membrane undergoes which of the following changes in charge?
