哺乳动物内耳中外毛细胞主动性活动过程有放大声音作用和很好的频率选择作用。主动性活动过程可分为二个部分 :1机械电转换过程 ;2电机械转换过程。前者为静纤毛弯曲产生接受电流 ,后者电流引起细胞壁蛋白发生长度改变。这些过程涉及到外毛细胞壁的结构。该文作者通过研究 ,提 Mammalian internal and external hair cell activity in the hair cells have amplified the sound effect and a good frequency of selection. Initiative activities can be divided into two parts: 1 mechanical and electrical conversion process; 2 electrical mechanical conversion process. The former produces a receptive current due to ciliary bends and the latter current causes a change in the length of the cell wall protein. These processes involve the structure of the outer hair cell wall. The author through research, mention
