Vedclass · Answer

(D) Nerve conduction,or the transmission of a nerve impulse along an axon,primarily relies on the movement of $Na^+$ and $K^+$ ions across the neuronal membrane.During the resting state,the axonal membrane is more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.When a stimulus is applied,the membrane becomes permeable to $Na^+$ ions,leading to a rapid influx of $Na^+$ into the cell,which causes depolarization.Following this,the membrane becomes permeable to $K^+$ ions,leading to an efflux of $K^+$ out of the cell,which causes repolarization.Thus,$Na^+$ and $K^+$ are the essential ions for the generation and conduction of nerve impulses.
