Vestibular apparatus was investigated in rats subjected to weightlessness for 19.5 days in the satelite "Cosmos-782" and experienced acceleration on launching and landing. Some structural and functional changes were noted. They were seen in otolith clinging to the utricular receptor surface and in the peripheral arrangement of the nucleolus in the nuclei of the receptor cells. It is also possible that increased edema of the vestibular tissue resulted in destruction of some receptor cells, and within the otolith--changes in the form and structure of otoconia. In the horizontal crista the cupula was separated.
对搭乘卫星“宇宙-782”失重19.5天且在发射和着陆时经历加速度的大鼠的前庭器官进行了研究。观察到了一些结构和功能上的变化。这些变化见于耳石附着于椭圆囊感受器表面以及感受器细胞核内核仁的周边排列。前庭组织水肿加剧也可能导致一些感受器细胞遭到破坏，并且在耳石内部——耳石晶体的形态和结构发生了变化。在水平嵴中，嵴帽出现了分离。
