Fine structure of the tissue lining the cochlear perilymphatic space against the bony labyrinthine capsule

The perilymphatic tissue covering the bony labyrinthine capsule was studied in chinchillas by help of the thin-section and the freeze-fracture methods. Among the extremely flat and extended cells there were demonstrated fasciae occludentes and maculae communicantes. It is supposed that the perilymphatic tissue is arachnoidal tissue, too.
