1. Tectorial membrane

   The tectoria membrane (TM) is one of two acellular membranes in the cochlea of the inner ear, the other being the basilar membrane (BM). "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 (transversally) and overlies the auditory teeth of Huschke with its inside edge attached to the spiral limbus. The marginal zone is the thickest (transversally) and is divided from the middle zone by Hensen's 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.

1. Tectorial membrane

   The tectorial membrane is one of two acellular gels in the cochlea of the inner ear, the other being the basilar membrane. The TM is located above the sulcus spiralis internus 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 Hensen's 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. The TM is a gel-like structure containing 97% water. Its dry weight is composed of collagen, non-collagenous glycoproteins and proteoglycans. Three inner-ear specific glycoproteins are expressed in the TM, α-tectorin, β-tectorin and otogelin. Of these proteins α-tectorin and β-tectorin form the striated sheet matrix that regularly organises the collagen fibres. Due to the increased structural complexity of the TM relative to other acullular gels, its mechanical properties are consequently significantly more complex. They have been experimentally shown to be radially and longitudinally anisotropic and to exhibit viscoelastic properties.-/-

1. Tectorial Membrane

   A membrane, attached to the bony SPIRAL LAMINA, overlying and coupling with the hair cells of the ORGAN OF CORTI in the inner ear. It is a glycoprotein-rich keratin-like layer containing fibrils embedded in a dense amorphous substance.
