Webhair cell 1. any of the sensory receptors for hearing, located in the organ of Corti within the cochlea of the inner ear. They respond to vibrations of the basilar membrane via movement of the fine hairlike structures ( stereocilia) that protrude from them. In humans, there are 12,000 outer hair cells and 3,500 inner hair cells. WebThe inner hair cells are the primary auditory receptors and exist in a single row, numbering approximately 3,500. The stereocilia from inner hair cells extend into small dimples on the tectorial membrane’s lower surface. The outer hair cells are arranged in three or four rows.
