Sound entering the inner ear stimulates different regions of the basilar membrane, depending on sound frequency. Hair cells in the stimulated regions are excited by the resulting shearing action between the …
WebIn 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. When tension increases, the flow of ions across the membrane into the hair cell rises as well. WebApr 1, 2024 · Mainly found in mammals. Also, aids in awareness of positioning and surrounding. Complete Step by Step Answer: - The Tectorial membrane is one of the inner …
WebSound waves cause the basilar membrane to move relative to the tectorial membrane. The cilia of the hair cells bend when contact is made to the tectorial membrane and the hair cell discharges. The human cochlea contains approximately 3500 inner hair cells (those lying on the inside of the cochlear coil) and 12,000 outer hair cells (those lying on the outside of … WebThe tectorial membrane (TM) is widely believed to play a critical role in determining the remarkable sensitivity and frequency selectivity that are hallmarks of mammalian hearing. …
WebNov 19, 2024 · The basilar membrane, part of the organ of Corti, responds to motion in the scala vestibuli by the movement of hair cells against the tectorial membrane. The movement of the tectorial membrane ...
WebThe motion of the traveling wave initiates sensory transduction by displacing the hair cells that sit atop the basilar membrane.Because these structures are anchored at different positions, the vertical component of the traveling wave is translated into a shearing motion between the basilar membrane and the overlying tectorial membrane (Figure 13.6). ... philhealth hiring processWebArranged on the surface of the basilar membrane are orderly rows of the sensory hair cells, which generate nerve impulses in response to sound vibrations. Together with their supporting cells they form a complex neuroepithelium called the basilar papilla, or organ of Corti.
