Anatomical terminology

The bony labyrinth (osseous labyrinth) is the rigid outer wall of the inner ear. It consists of three parts: the vestibule, semicircular canals, and cochlea. These are cavities hollowed out of the substance of the bone, and lined by periosteum. They contain a clear fluid, the perilymph, in which the membranous labyrinth is situated.
