  2. Inner ear regeneration - Wikipedia

    en.wikipedia.org/wiki/Inner_Ear_Regeneration

    Inner ear regeneration is the biological process by which the hair cells and supporting cells (i.e. Hensen's cells and Deiters cells) of the ear proliferate (cell proliferation) and regrow after hair cell injury. This process depends on communication between supporting cells and the brain.

  3. Hair cell - Wikipedia

    en.wikipedia.org/wiki/Hair_cell

    Mammalian cochlear hair cells are of two anatomically and functionally distinct types, known as outer, and inner hair cells. Damage to these hair cells results in decreased hearing sensitivity, and because the inner ear hair cells cannot regenerate, this damage is permanent. [4]

  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. Hensen's cell - Wikipedia

    en.wikipedia.org/wiki/Hensen's_cell

    [5] [6] Furthermore, Hensen's cells are also able to regenerate the damaged hair cells in some vertebrates; they undergo phagocytosis to eject the dead or injured hair cells, and reproduce both new hair cells and supporting cells into the cell cycle. One of the reasons is that the supporting cells are differentiated by the embryonic hair cells ...

  6. Ceruminous gland - Wikipedia

    en.wikipedia.org/wiki/Ceruminous_gland

    Here they produce cerumen, or earwax, by mixing their secretion with sebum and dead epidermal cells. Cerumen keeps the eardrum pliable, lubricates and cleans the external auditory canal , waterproofs the canal, kills bacteria, and serves as a barrier to trap foreign particles (dust, fungal spores, etc.) by coating the guard hairs of the ear ...

  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. GJB6 - Wikipedia

    en.wikipedia.org/wiki/GJB6

    Gap junction channels are only found between cochlear supporting cells. [14] While gap junctions in the inner ear are critically involved in potassium recycling to the endolymph, connexin expression in the supporting cells surrounding the organ of Corti have been found to support epithelial tissue lesion repair following loss of sensory hair ...

  9. Crista ampullaris - Wikipedia

    en.wikipedia.org/wiki/Crista_ampullaris

    The crista ampullaris itself is a cone-shaped structure, covered in receptor cells called "hair cells". Covering the crista ampullaris is a gelatinous mass called the cupula. Upon angular acceleration (rotation), the endolymph within the semicircular duct deflects the cupula against the hair cells of the crista ampullaris.
