Comments "The human organ of Corti harbors ~ 16,000 hair cells that are patterned in one row of inner hair cells (IHCs) and three rows of outer hair cells (OHCs Fig. 1, B and C). Each hair cell contains at the apical surface its mechanically sensitive organelle, the hair bundle, which consists of dozens of stereocilia (Fig. 1, C and D Fig. 2 A). An extracellular matrix, the tectorial membrane, covers the apical surface of the organ of Corti and is attached to the stereociliary bundles of OHCs. The cell bodies of hair cells form tight connections with support cells, which in turn adhere at their basal surface to an additional extracellular matrix, the basilar membrane (Fig. 1 B)."
