目的 :探讨豚鼠椭圆囊斑毛细胞静纤毛束间的相互连接形式及其生理意义。方法 :用扫描电镜和透射电镜观察豚鼠椭圆囊斑毛细胞静纤毛束间的相互连接。结果 :豚鼠椭圆囊斑毛细胞静纤毛束间存在 3种相互连接形式 :1顶部连接 :自短纤毛顶至长纤毛的上行连接 ;2侧连接 :同行静纤毛间的云雾状连接 ;3行间连接 :邻近行间的连接。结论 :3种连接的存在可将纤毛束连为一体。推测当纤毛偏转时 ,所有静纤毛可能形成一个整体依次移动 ,牵拉或放松顶部连接 ,从而改变纤毛顶端膜机械门控离子通道的电导 ,使细胞膜离子通透性改变 ,细胞膜去极化或超极化 ,导致神经兴奋或抑制。
OBJECTIVE: To investigate the interconnected forms and their physiological significance of the pilus ciliated tufts of guinea pigs. Methods: Scanning electron microscope (SEM) and transmission electron microscopy (TEM) were used to observe the interconnections of the pilus ciliated piloseblasts in guinea pigs. RESULTS: There were three types of interconnections between the ciliated tufts of the pterygial cells in the guinea pig: 1 Top connection: Upstream connection from the top of the fibril to the long cilia; 2-side connection: Cloud- Connection: the connection between adjacent lines. Conclusion: The presence of three types of connectives allows cilia bundles to be integrated. Speculated that when the cilia deflection, all the static cilia may form an overall move in order to pull or relax the top of the connection, thereby changing the ciliary membrane mechanical gated ion channel conductivity, the membrane ion permeability change, cell membrane depolarization or ultra Polarization causes nervous excitement or depression.
