Depolarization of the hair cells in the cochlea is caused primarily by the flow of

1.K+ into the hair cell
2.Na+ into the hair cell
3.K+ out of the hair cell
4.Ca2+ into the hair cell

exp:

When the hair cells are bent, K+ selective channels open, K+ flows into the cell, and the cell depolarizes. This unusual situation occurs because the apical surface of the hair cells, on which the stereocilia are located, is bathed in endolymph, which contains a high concentration of K+.
