Auditory hair cells are specialized sensory cells located in the inner ear, specifically within the cochlea. They play a crucial role in the process of hearing by converting sound vibrations into electrical signals. These cells have tiny hair-like structures called stereocilia that move in response to sound waves, triggering the release of neurotransmitters. When the stereocilia bend, they open ion channels, allowing ions to flow into the cell. This generates an electrical signal that travels along the auditory nerve to the brain, where it is interpreted as sound. Damage to auditory hair cells can lead to hearing loss, highlighting their importance in auditory function.
