Auditory sensory cells of organ of Corti, usually placed in one row medially to the core of spongy bone (the modiolus). Inner hair cells are in fewer numbers than the OUTER AUDITORY HAIR CELLS, and their stereocilia are approximately twice as thick as those of the outer hair cells.
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 hair cell bodies and their apical stereocilia increase, allowing differential responses to various frequencies of sound.
