Anatomical terminology

Scala vestibuli or vestibular duct is a perilymph-filled cavity inside the cochlea of the inner ear that conducts sound vibrations to the scala media.

It is separated from the scala media by Reissner's membrane and extends from the vestibule of the ear to the helicotrema where it joins scala tympani.
