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.
Damage to hair cells can cause damage to the vestibular system and therefore cause difficulties in balancing. However, other vertebrates, such as the frequently studied zebrafish, and birds have hair cells that can regenerate. [5] [6] The human cochlea contains on the order of 3,500 inner hair cells and 12,000 outer hair cells at birth. [7]
Deflections of the stereocilia in the opposite direction toward the shortest stereocilia causes transduction channels to close. In this situation, the hair cells become hyperpolarized and the nerve afferents are not excited. [7] [8] [9] There are two different types of fluid that surround the hair cells of the inner ear.

Ear hair generally refers to the terminal hair arising from follicles inside the external auditory meatus in humans. [2] In its broader sense, ear hair may also include the fine vellus hair covering much of the ear, particularly at the prominent parts of the anterior ear, or even the abnormal hair growth as seen in hypertrichosis and hirsutism.
Basset hounds and beagles are only just the beginning. And they're all irresistibly cute. The post 12 Dogs with Floppy Ears That Are Irresistibly Cute appeared first on Reader's Digest.
Tip links are extracellular filaments that connect stereocilia to each other or to the kinocilium in the hair cells of the inner ear. [ 1 ] [ 2 ] Mechanotransduction is thought to occur at the site of the tip links, which connect to spring-gated ion channels. [ 3 ]
Together with its conjugate base superoxide, hydroperoxyl is an important reactive oxygen species.Unlike • O − 2, which has reducing properties, HO • 2 can act as an oxidant in a number of biologically important reactions, such as the abstraction of hydrogen atoms from tocopherol and polyunstaturated fatty acids in the lipid bilayer.
