The bony labyrinth is a complex structure located within the inner ear, composed of a series of interconnected cavities and channels. It is made of hard, bony tissue and houses the delicate structures responsible for hearing and balance. The bony labyrinth is divided into three main parts: the cochlea, the vestibule, and the semicircular canals. Surrounding the bony labyrinth is a fluid called perilymph, which plays a crucial role in transmitting sound vibrations and maintaining balance. Inside the bony labyrinth lies the membranous labyrinth, which contains another fluid called endolymph. Together, these structures work to process auditory and vestibular information, allowing us to hear and maintain our equilibrium.
