labyrinth /lab·y·rinth/ (lab´ĭ-rinth) the internal ear, made up of the vestibule, cochlea, and canals. labyrin´thine
bony labyrinth the bony part of the internal ear. cochlear labyrinth the part of the membranous labyrinth that includes the perilymphatic space and the cochlear duct. endolymphatic labyrinth membranous l. ethmoidal labyrinth either of the paired lateral masses of the ethmoid bone, which contain many thin-walled cellular cavities. membranous labyrinth a system of communicating epithelial sacs and ducts within the bony labyrinth, containing the endolymph. osseous labyrinth bony l. perilymphatic labyrinth perilymphatic space. vestibular labyrinth the part of the membranous labyrinth that includes the utricle and saccule and the semicircular ducts.
Labyrinth The bony cavity of the inner ear. Mentioned in: Labyrinthitis
labyrinth. See internal ear. labyrinth [lab´ĭ-rinth] the inner ear, consisting of the vestibule, cochlea, and semicircular canals. The cochlea is concerned with hearing and the vestibule and semicircular canals with the sense of equilibrium. (See also color plates.) adj., adj labyrin´thine. The bony portion of the labyrinth (osseous labyrinth) is composed of a series of canals tunneled out of the temporal bone. Inside the osseous labyrinth is the membranous labyrinth, which conforms to the general shape of the osseous labyrinth but is much smaller. A fluid called perilymph fills the space (perilymphatic 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. The membranous labyrinth is divided into two parts: the cochlear labyrinth, which includes the perilymphatic space and the cochlear duct, and the vestibular labyrinth, which includes the utricle, saccule, and semicircular canals. Disorders of the inner ear, such as labyrinthitis and meniere's disease, are characterized by episodes of dizziness, tinnitus, and hearing loss. ethmoid labyrinth (ethmoidal labyrinth) either of the paired lateral masses of the ethmoid bone, consisting of numerous thin-walled cellular cavities, the ethmoidal cells.
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.
