Inner ear cells
WebbThe organ of Corti, or spiral organ, is the receptor organ for hearing and is located in the mammalian cochlea.This highly varied strip of epithelial cells allows for transduction of auditory signals into nerve impulses' action potential. Transduction occurs through vibrations of structures in the inner ear causing displacement of cochlear fluid and … Webb14 apr. 2024 · Repeated or prolonged exposure to loud noises can cause permanent damage to the sensitive hair cells within the inner ear. This can lead to loud noise ear damage, or noise-induced hearing loss (NIHL), a condition where a person gradually loses their ability to hear sounds in certain frequencies. Loud noise hearing loss, or NIHL, can …
