Question

Quizplus · Accepted Answer

Sodium and potassium ions are crucial in the transmission of the nerve impulse. As nerve impulses travel along the nerve cell, these ions move in and out of the cell membrane, creating a charge difference that allows the impulse to continue along the nerve fibers. Iron and nickel do not play a significant role in this process.
