  2. Hair cell - Wikipedia

    en.wikipedia.org/wiki/Hair_cell

    In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.

  3. Cochlear amplifier - Wikipedia

    en.wikipedia.org/wiki/Cochlear_amplifier

    The hair bundle motor operates by deflecting hair bundles in the positive direction and providing positive feedback of the basilar membrane, increasing the movement of the basilar membrane which increases the response to a signal. Two mechanisms have been proposed for this motor: fast adaptation, or channel re-closure, and slow adaptation.

  4. Organ of Corti - Wikipedia

    en.wikipedia.org/wiki/Organ_of_Corti

    The organ of Corti is located in the scala media of the cochlea of the inner ear between the vestibular duct and the tympanic duct and is composed of mechanosensory cells, known as hair cells. [2] Strategically positioned on the basilar membrane of the organ of Corti are three rows of outer hair cells (OHCs) and one row of inner hair cells ...

  5. Cochlea - Wikipedia

    en.wikipedia.org/wiki/Cochlea

    The stria vascularis is a rich bed of capillaries and secretory cells; Reissner's membrane is a thin membrane that separates endolymph from perilymph; and the basilar membrane is a mechanically somewhat stiff membrane, supporting the receptor organ for hearing, the organ of Corti, and determines the mechanical wave propagation properties of the ...

  6. Tonotopy - Wikipedia

    en.wikipedia.org/wiki/Tonotopy

    Different regions of the basilar membrane in the organ of Corti, the sound-sensitive portion of the cochlea, vibrate at different sinusoidal frequencies due to variations in thickness and width along the length of the membrane. Nerves that transmit information from different regions of the basilar membrane therefore encode frequency tonotopically.

  7. Inner ear - Wikipedia

    en.wikipedia.org/wiki/Inner_ear

    The hair cells are the primary auditory receptor cells and they are also known as auditory sensory cells, acoustic hair cells, auditory cells or cells of Corti. The organ of Corti is lined with a single row of inner hair cells and three rows of outer hair cells. The hair cells have a hair bundle at the apical surface of the cell.

  8. Kinocilium - Wikipedia

    en.wikipedia.org/wiki/Kinocilium

    One kinocilium is the longest cilium located on the hair cell next to 40–70 stereocilia. During movement of the body, the hair cell is depolarized when the stereocilia move toward the kinocilium. The depolarization of the hair cell causes neurotransmitter to be released and an increase in firing frequency of cranial nerve VIII. When the ...

  9. Stria vascularis of cochlear duct - Wikipedia

    en.wikipedia.org/wiki/Stria_vascularis_of...

    marginal cells, [1] which are involved in K + transport, and line the endolymphatic space of the scala media. intermediate cells, [1] which are pigment-containing cells scattered among capillaries. basal cells, [1] which separate the stria vascularis from the underlying spiral ligament. [2] They are connected to basal cells with gap junctions. [1]
