Depоlаrizаtiоn meаns that the inside оf the membrane is becoming more [positive] compared to resting membrane potential. When the membrane is stimulated, Na+ channels [open] and Na+ rushes [into] the cell. This causes [depolarization]. When the charge inside the cell reaches +30 mvs, the Na+ channels [close] and the K+ channels [open]. K+ rushes [out] the cell. Finally the Na+/K+ pump uses [ATP] to move Na+ back [outof] the cell and K+ back [intoa] the cell.
