前庭器官的毛细胞纤毛中的一种。对前庭器官的毛细胞去极化和超极化起直接作用。
目的探讨耳蜗毛细胞静纤毛束变异与听功能改变的关系。
Objective To study the variant stereociliary bundles of cochlear out hair cell(OHC)and their relationship with auditory function.
声音振动使静纤毛轻微弯曲，造成机械振动，机械振动变成一种电化学信号，最后大脑将其理解为声音。
Sound vibrations cause the stereocilia to bend slightly, causing mechanical vibrations that are then converted into an electrochemical signal that the brain interprets as sound.
方法测定2 0只豚鼠听性脑干反应（ABR）阈和畸变产物耳声发射（DPOAE）振幅，观察耳蜗毛细胞静纤毛变异形态，计数变异的毛细胞数目。
Methods Auditory brainstem response(ABR)and otoacoustic emission of distortion products(DPOAE)were assayed to 20 guinea pigs, then variant hair cells were observed and counted.
