Define bony labyrinth??

The bony labyrinth refers to the rigid, bony structure within the inner ear that houses and protects the delicate structures responsible for hearing and balance. It is composed of three main parts: the cochlea, the vestibule, and the semicircular canals. The cochlea is responsible for hearing, while the vestibule and semicircular canals are involved in maintaining balance and spatial orientation. The bony labyrinth is filled with a fluid called perilymph, which helps transmit sound and movement signals to the sensory cells within the inner ear.
