State
The fluid-filled cochlea houses the basilar membrane and the organ of Corti, where hair cells transduce fluid pressure waves into electrical signals via bending stereocilia.
Show
Bending stereocilia toward their tallest neighbor opens gated ion channels, depolarizing the hair cell.
Watch for
Inner hair cells, not the more numerous outer hair cells, carry most of the auditory information to the brain.
