Specifically, the active amplification function of the outer hair cells is very sensitive to damage from exposure to trauma from overly-loud sounds or to certain ototoxic drugs.
Research on the regrowth of cochlear cells may lead to medical treatments that restore hearing. Unlike birds and fish, humans and other mammals are generally incapable of regrowing the cells of the inner ear that convert sound into neural signals when those cells are damaged by age or disease. Researchers are making progress in gene therapy and stem-cell therapy that may allow the damaged cells to be regenerated. Because hair cells of auditory and vestibular systems in birds an… WebApr 12, 2024 · Each crista is composed of the special sensory receptor cells, called the hair cells.

WebMay 3, 2024 · Mammalian inner ear and fish lateral line sensory hair cells (HCs) detect fluid motion to transduce environmental signals. Actively maintained ionic homeostasis of the mammalian inner ear endolymph is essential for HC function. In contrast, fish lateral line HCs are exposed to the fluctuating ionic composition of the aqueous environment. covid19 data qldWebhair cells, regenerated lost sensory cells in their vestibular systems. Interestingly enough, the regenerated hair cells developed an active afferent nerve supply, which supports the notion that their sensory organ had recovered its function (Walshe et al., 2003).
