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 to a nerve fibre,the permeability of the membrane to $Na^+$ ions increases significantly. This leads to a rapid influx of $Na^+$ ions into the cell. As a result,the inside of the membrane shifts from a negative potential to a positive potential. This change in electrical potential is known as depolarization. Therefore,upon stimulation,the inside of the membrane becomes positively charged.

When a nerve fibre is stimulated,the inside of the membrane becomes:
