Labyrinth
The bony cavity of the inner ear.
Mentioned in: Labyrinthitis
labyrinth.
See internal ear.
labyrinth
the system of interconnecting cavities or canals of the internal ear, consisting of the vestibule, cochlea and semicircular canals.
The cochlea is concerned with hearing, and the vestibule and semicircular canals with equilibrium (sense of balance).
bony labyrinth
the bony or osseous labyrinth is composed of a series of canals tunneled out of the temporal bone.
ethmoid labyrinth, ethmoidal labyrinth
either of the paired lateral masses of the ethmoid bone, consisting of numerous thin-walled cellular cavities, the ethmoidal cells.
membranous labyrinth
inside the osseous labyrinth is the membranous labyrinth, which conforms to the general shape of the osseous labyrinth but is smaller. A fluid called perilymph fills the space between the osseous and membranous labyrinths. Fluid inside the membranous labyrinth is called endolymph. These fluids play an important role in the transmission of sound waves and the maintenance of body balance.
osseous labyrinth
a complex excavation in the petrous part of the temporal bone which houses the membranous labyrinth.
