inner hair cell

sensory cells in the organ of Corti in synaptic contact with sensory as well as efferent fibers of the auditory nerve; there is a single row of flask-shaped inner hair cells tightly surrounded by supporting interphalangeal cells; the apical end of each cell is anchored to the cuticular plate and about 100 stereocilia arranged in a more or less linear (or shallow) "U" pattern extend from the cell's surface through the cuticular plate into the endolymphic space inferior to the tectorial membrane.

Histopathologic studies have shown that outer hair cells are more sensitive to ototoxic injury than are inner hair cells. We also know that the aminoglycosides are transported into the hair cells themselves, but they probably do not concentrate there.
At E15.5, myosin7a was clearly expressed in developing inner hair cells, but not in the developing outer hair cells (OHCs) at the basal end of the cochlea (Figure 2, A4-A5).
Hearing starts with the transmission of sound by inner hair cells in the ear.
The hypothesis that subjective tinnitus is primarily caused by glutamate excitotoxicity at the synapses between inner hair cells and their afferents in the cochlea has been confirmed.
The outer hair cells are much more susceptible to injury than are the inner hair cells. (6) Among the outer hair cells, those in the inner row are the most susceptible; those in the middle row are less susceptible, and those in the outer row are the least susceptible (figure 1).
The fibers that originate in the lateral area of the upper olivary complex extend through the ipsilateral cochlea and end under the nerve fibers on the inner hair cells. The fibers that originate in the median area of the upper olivary complex extend through the contralateral cochlea down to the outer hair cells.
Inner hair cells (IHCs) and outer hair cells (OHCs) are two types of sensory cells in the mammalian cochlea.
In mammalian inner ear, transduction by Ad vectors is organ (cochlea versus vestibule), cell type (inner hair cells (IHCs), outer hair cells (OHCs), and supporting cells (SCs)), region (base, middle, and apical turns), and age dependence.
