Basilar fibre vibration Shearing force created in Reticular lamina tectorial membrane Bending of the stereocilia Opening of K channels K enter hair cells Depolarization Of hair cells. Depolarization then open voltage gated Ca channels. Ca enter hair cells Glutamate NT is released at the synapse Glutamate causes excitation of the VIIIth nerve
