1. hair cells, auditory Sensory cells in the organ of Corti, characterized by their apical stereocilia (hair-like projections). The inner and outer hair cells, as defined by their proximity to the core of spongy bone (the modiolus), change morphologically along the cochlea. Towards the cochlear apex, the length of haircell bodies and their apical stereocilia increase, allowing differential responses to various frequencies of sound.
