ⓘ Tectorial membrane

The tectorial membrane is one of two acellular membranes in the cochlea of the inner ear, the other being the basilar membrane. "Tectorial" in anatomy means forming a cover. The TM is located above the spiral limbus and the spiral organ of Corti and extends along the longitudinal length of the cochlea parallel to the BM. Radially the TM is divided into three zones, the limbal, middle and marginal zones. Of these the limbal zone is the thinnest and overlies the auditory teeth of Huschke with its inside edge attached to the spiral limbus. The marginal zone is the thickest and is divided from the middle zone by Hensens Stripe. It overlies the sensory inner hair cells and electrically-motile outer hair cells of the organ of Corti and during acoustic stimulation stimulates the inner hair cells through fluid coupling, and the outer hair cells via direct connection to their tallest stereocilia.
