Detailed explanation-1: -The bony labyrinth can be divided into four areas: the vestibule, the semicircular canals, the cochlea, and the internal acoustic meatus.

Detailed explanation-2: -The bony labyrinth (also osseous labyrinth or otic capsule) is the rigid, bony outer wall of the inner ear in the temporal bone. 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.

Detailed explanation-3: -The bony labyrinth consists of a central chamber, the vestibule, the three semicircular canals, and the spiral cochlea.

Detailed explanation-4: -The cochlea is a bony, spiral-shaped chamber that contains the cochlear duct of the membranous labyrinth. The sense of hearing is provided by receptors within the cochlear duct. A pair of perilymph-filled chambers is found on each side of the duct.
