The ultrastructure of the perilymphatic space of the guinea pig semicircular canal was examined, using thin sectioning, scanning electron microscopy and freeze-fracture methods. The perilymphatic space was divided into two parts: an area of fibrous matrix and an area of fibroblasts with bundles of fine filaments. In the area of fibroblasts, cell processes and filament bundles formed a meshed pattern. The cell processes were interconnected with each other by both intermediary and gap junctions. The inner surface of the osseous semicircular canal was covered with multilayers of cell processes of both fibroblasts and mesothelial cells. The fact that tight and gap junctions were observed between the cell processes suggests a functional significance in these structures.
运用超薄切片、扫描电子显微镜和冷冻蚀刻方法，对豚鼠半规管外淋巴间隙的超微结构进行了研究。外淋巴间隙分为两部分：纤维基质区和成纤维细胞区，成纤维细胞区有细纤维束。在成纤维细胞区，细胞突起和纤维束形成网状图案。细胞突起通过中间连接和缝隙连接相互连接。骨半规管的内表面覆盖着成纤维细胞和间皮细胞的多层细胞突起。在细胞突起之间观察到紧密连接和缝隙连接，这一事实表明这些结构具有功能意义。
