tectorial membranes การใช้

• The stereocilia found on OHCs are in contact with the tectorial membrane.
• These waves exert a pressure on the basilar and tectorial membranes of the cochlea which vibrate in response to sound waves of different frequencies.
• Thus, the RM up to the outer edge of the tectorial membrane and does not extend unto the surface of the organ of corti.
• The hair cells develop from the lateral and medial ridges of the cochlear duct, which together with the tectorial membrane make up the organ of Corti.
• Through the foramen passes the medulla oblongata and its membranes, the accessory nerves, the posterior spinal arteries, and the tectorial membrane and alar ligaments.
• The tectorial membrane supports the remaining IHC and OHC . Tectorial membrane helps facilitate cochlear amplification by stimulating OHC ( direct ) and IHC ( via endolymph vibrations ).

• When the basilar membrane is driven upward, shear between the hair cells and the tectorial membrane deflects hair bundles in the excitatory direction, toward their tall edge.
• One unavoidable difference, however, is that while all hair cells are attached to a tectorial membrane in birds, only the outer hair cells are attached to the tectorial membrane in mammals.

• Outer hair cells ( OHCs ) contribute to the structure of the Organ of Corti, which is situated between the basilar membrane and the tectorial membrane within the cochlea ( See Figure 3 ).
• The "'tectorial membrane "'( TM ) is one of two acellular membranes in the cochlea of the inner ear, the other being the basilar membrane ( BM ).
• Basilar Membrane motion causes a shearing motion between the reticular lamina and the tectorial membrane, thereby activating the mechano-sensory apparatus of the hair bundle, which in turn generates a receptor potential in the hair cells.
• In the cochlea, a shearing movement between the tectorial membrane and the basilar membrane deflects the stereocilia, affecting the tension on the tip-link filaments, which then open and close the non-specific ion channels.
• The cochlea thus acts as an'acoustic prism', distributing the energy of each tectorial membrane and the reticular lamina of the organ of Corti, the hair bundles that link the two are deflected, which initiates mechano-electrical transduction.
• The " upper surface ", constitutes the lower half of clivus, presents a broad, shallow groove which inclines upward and forward from the foramen magnum; it supports the medulla oblongata, and near the margin of the foramen magnum gives attachment to the tectorial membrane
