WebThe outer hair cell stereocilia are tiny, thin projections that protrude from the surface of the outer hair cells. These stereocilia are extremely sensitive and are able to detect even the smallest of vibrations. The outer hair cell stereocilia are moved up and down when the cells move up and down, in response to sound waves that enter the ear. WebSep 26, 2024 · Hair cells are small sensors in our ears that receive sound signals and send them off to the brain. Each ear has roughly 15,000 hair cells in total. Around 3,000 of these hair cells are inner hair cells, and the other 12,000 are outer hair cells. Inner hair cells receive the sound signals and translate them, and outer hair cells work to amplify ...
