抄録

Scanning electron microscopic observations were performed on the sensory epithelium of the bullfrog inner ear. <br>1.The membranous folding on a kinocilium was observed in the amphibian and basilar papilla.It was spiral along the long axis of the kinocilial stem.In the vestibular sensory epithelium the folding was incomplete. <br>2.It was suggested that the kinocilia of the sensory epithelium move spirally like the flagella of the spermatozoa.A local stream of the lymph may take place in the sheaths of the tectorial body and cupula. <br>3.In the amphibian and basilar papilla, each sensory cell was surrounded by the support-ing cells in independent lymphatic environment. <br>4.A round epithelial macula was observed on both sides of the ampullar crista of the semicircular canal.Double blephaloblasts were observed on each of the macula.Groups of microvilli were seen on the macula.It was assumed that the macula might be the sensory epithelium.
