| Pronunciation (US): |  | (GB): | |
Irregular inflected form: cochleae
I. (noun)
Sense 1
Meaning:
The snail-shaped tube (in the inner ear coiled around the modiolus) where sound vibrations are converted into nerve impulses by the organ of Corti
Classified under:
Hypernyms ("cochlea" is a kind of...):
tube; tube-shaped structure ((anatomy) any hollow cylindrical body structure)
Meronyms (parts of "cochlea"):
basilar membrane (a membrane in the cochlea that supports the organ of Corti)
modiolus (the central conical bony pillar of the cochlea)
organ of Corti (the hearing organ of the inner ear; contains receptors that respond to sound waves)
Holonyms ("cochlea" is a part of...):
inner ear; internal ear; labyrinth (a complex system of interconnecting cavities; concerned with hearing and equilibrium)
Context examples:

The auditory nerve conveys impulses from the cochlea of the inner ear to the auditory nuclei of the brainstem.
(Murine Vestibulocochlear Nerve, NCI Thesaurus)
A cell situated on one of three of the most outer layers of the basilar membrane of the cochlea.
(Outer Hair Cell of the Organ of the Corti, NCI Thesaurus)
A cell situated on the inner most layer of the basilar membrane of the cochlea.
(Inner Hair Cell of the Organ of the Corti, NCI Thesaurus)
The organ of hearing: composed of the external ear, which includes the auricle and the external acoustic, or auditory, meatus; the middle ear, or the tympanic cavity with its ossicles; and the internal ear or inner ear, or labyrinth, which includes the semicircular canals, vestibule, and cochlea.

(Ebselen-containing Oral Capsule SPI-1005, NCI Thesaurus)
The team examined the effect of noise on structural damage to hair cells and other parts of the cochlea.
(Protein involved in hearing loss recovery, NIH)
Hair cells are spread across a flat surface called the basilar membrane, which is rolled like a carpet and tucked into a snail shell-shaped structure in the inner ear called the cochlea.
(Hearing different frequencies, NIH)
When the cochlea moves in response to sound, a slight shearing force occurs between the basilar and tectorial membranes, the stereocilia bend and send electrical impulses to the brain via the eighth cranial nerve.
(Inner Hair Cell of the Organ of the Corti, NCI Thesaurus)
Within the cochlea, thousands of sensory cells known as hair cells are arranged in inner and outer rows.
