vestibule, cochlea, and perilymph
The Bony labyrinth or osseous labyrinth consists of three parts: the vestibule, semicircular canals, and cochlea.
The bony labyrinth that is comprised of two functional parts: the cochlea for hearing, and the vestibular system for balance. The internal, or inner, ear consists pf a system of bony and rather tortuous chambers called the osseous, or bony, labyrinth, which is filled with an aqueous fluid called perilymph.
a tortuous anatomical structure; especially : the inner ear or its bony or membranous part -- see BONY LABYRINTH, MEMBRANOUS LABYRINTH ; the cavity in the petrous portion of the temporal bone that contains the membranous labyrinth of the inner ear -- called also osseous labyrinth
The ossicles of the middle ear are positioned and connected by miniature ligaments, tendons, and joints. The cochlea, semicircular canals, and vestibule of the inner ear are linked. They are all fluid filled, and encased and protected inside the thickness of the skulls temporal bone. Together they occupy the series of tunnels and chambers known as the osseous labyrinth.
If you are refering to the ear. It is the Vestibule, Cochlea, and semi circular canal.
Osseous means bony and contusion means bruise.
Typically, it means age-related changes in the bony parts. It's part of life.
Osteonecrosis means bony necrosis.
Osseous
The semicircular canals, the vestibule, and the cochlea, which are subdivisions of the bony labyrinth. Semicircular canals and the vestibule contain receptors for equilibrium and the cochlea contains receptors for hearing.
bone, or osseous
Osseus tissue (bone) is classified as a connective tissue.
