inner hair cell การใช้

• The inner hair cells provide the main neural output of the cochlea.
• Notably, their expression predominates cochlea inner hair cells ( IHCs ).
• Nerve fiber innervation is much denser for inner hair cells than for outer hair cells.
• Efferent synapses occur on outer hair cells and on afferent axons under inner hair cells.
• Type I neurons innervate inner hair cells.
• A radial fiber bundle acts as an intermediary between Type I neurons and inner hair cells.
• When both the outer and inner hair cells are damaged the filter is broader on both sides.
• Additional projections form the lateral olivocochlear bundle ( LOC ), which innervates cochlear inner hair cells.
• This, in turn, influences the deflection of the hair bundles of the inner hair cells.
• Inner hair cells, like the photoreceptor cells of the eye, show a spikes typical of other neurons.
• Efferent synapses occur on outer hair cells and on afferent ( towards the brain ) dendrites under inner hair cells
• The organ of Corti is lined with a single row of inner hair cells and three rows of outer hair cells.
• Three rows consist of outer hair cells ( OHCs ) and one row consists of inner hair cells ( IHCs ).
• In birds, for instance, instead of outer and inner hair cells, there are tall and short hair cells.
• A single inner hair cell is innervated by numerous nerve fibers, whereas a single nerve fiber innervates many outer hair cells.
• Inner hair cell nerve fibers are also very heavily myelinated, which is in contrast to the unmyelinated outer hair cell nerve fibers.
• The tunnel of corti, which runs through the Organ of Corti, divides the OHCs and the inner hair cells ( IHCs ).
• The inner hair cells are the sensory receptors while the outer hair cells are usually from efferent axons originating from cells in the superior olivary complex.
• The inner hair cells are the primary sensory receptors and a significant amount of the sensory input to the auditory cortex occurs from these hair cells.
• Afferent neurons innervate cochlear inner hair cells, at synapses where the neurotransmitter glutamate communicates signals from the hair cells to the dendrites of the primary auditory neurons.
