在硬骨鱼(Burbot)的前庭和侧线器官中，从每个感受器细胞的顶端伸出的感觉毛束由若干个立体纤毛和位于该束外围的一个动纤毛组成。本文描述了动纤毛及其基底层的超微结构。结果发现，动纤毛的形态极化是由于其组成纤维的不对称排列，而基底体的不对称排列是由于基足的存在。动纤毛的外周纤维5和6和基底体的基底足的方向远离静纤毛，即方向与兴奋性刺激的方向一致。从方向敏感性的角度对这些发现进行了讨论。
The bundle of sensory hairs protruding from the top of each receptor cell in the vestibular and lateral line organs in the teleost fish (burbot) Lota vulgaris is composed of a number of stereocilia and one kinocilium located in the periphery of the bundle. The ultrastructure of the kinocilium and its basal body is described. It is found that the kinocilium is morphologically polarized by the asymmetric arrangement of its component fibers and of the basal body by the presence of a basal foot. Peripheral fibers 5 and 6 of the kinocilium and the basal foot of the basal body are oriented away from the stereocilia; that is, in a direction coinciding with the direction of excitatory stimulation. The findings are discussed in terms of directional sensitivity.
