Webtectorial membrane: The thin, jelly-like membrane projecting from the vestibular lip of the osseous spiral lamina and overlying the spiral organ of Corti of the ear. See also: membrane WebC1. (c) 2. The tereocilia of the outer hair cells are linked to the tectorial membrane, which is a gelatinous layer that sits atop the basilar membrane of the cochlea. The basilar membrane is the outermost layer of the cochlea. Incoming sound waves cause the basilar membrane to vibrate, and this vibration is communicated to the tectorial membrane.

Tectorial membrane Definition & Meaning Merriam-Webster …

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 … See more The TM is a gel-like structure containing 97% water. Its dry weight is composed of collagen (50%), non-collagenous glycoproteins (25%) and proteoglycans (25%). Three inner-ear specific glycoproteins are … See more The mechanical role of the tectorial membrane in hearing is yet to be fully understood, and traditionally was neglected or downplayed in many models of the cochlea. … See more • Diagram at une.edu • Animation at bioanim.com • Histology at KUMC eye_ear-ear03 See more • Floor of ductus cochlearis. • Cross section of the cochlea.

WebApr 3, 2024 · The organ of Corti lies on the basilar membrane, and is the organ responsible for converting these vibrations into electrochemical signals. There are stereocilia that lie on the organ of Corti. Their tips go into a gel like layer called the tectorial membrane. WebThe tectorial membrane was found to attach much more superiorly than previously described and was found to be firmly adherent to the cranial base and body of the axis but not to the posterior aspect of the odontoid process. The mean thickness of this membrane was found to be 1 mm. Flexion of the head made the tectorial membrane fully taut at 15 ... how can we combat poverty
