Quizplus · Accepted Answer

Potassium ions move into the hair cells from the endolymph when potassium channels open, leading to depolarization of the cell. This is because the endolymph has a high concentration of potassium, creating a gradient that drives potassium into the cells, changing their membrane potential.
