A cochlear implant is a surgically implanted electronic device that can help provide a sense of sound to a person who is profoundly deaf or severely hard of hearing
An electrode or electrodes placed in the cochlea and attached to an induction coil buried under the skin near the ear In association with a unit worn on the body, it provides limited hearing to those who cannot benefit from conventional hearing aids
An electronic apparatus that allows people with severe hearing loss to recognize some sounds, especially speech sounds, and that consists chiefly of a microphone and receiver, a processor that converts speech into electronic signals, and an array of electrodes that transmit the signals to the auditory nerve in the inner ear
medical device that bypasses damaged structures in the inner ear and directly stimulates auditory nerve to allow some deaf individuals to learn to hear and interpret sounds and speech
medical device that bypasses damaged structures in the inner ear and directly stimulates the auditory nerve, allowing some deaf individuals to learn to hear and interpret sounds and speech
- An electronic prosthetic device that is surgically placed in the inner ear and under the skin behind the ear for the purpose of providing useful sound perception via electrical stimulation of the auditory nerve
A device used for treating severe deafness that consists of one or more electrodes surgically implanted inside or outside the cochlea, an organ in the inner ear that transforms sound vibrations in the inner ear into nerve impulses for transmission to the brain Unlike a hearing aid, which amplifies sounds, the implant receives and passes on electrical signals
electronic device designed to stimulate the hearing mechanism It utilizes a coil of wire embedded under the skin behind the ear with an extension of wire into the fluid of the inner ear (cochlea) It is activated by an amplifier, similar to a body-type hearing aid, carried in a pocket There is sometimes a side benefit in that tinnitus is reduced

A coiled, fluid-filled chamber in the inner ear, containing the basilar membrane, where mechanical (sound) energy is converted into neural energy Resolution of a complex sound into its components occurs in the cochlea
The winding tubular cavity within the inner ear, shaped like a snail-shell; contains the organ of Corti, the end-organ of hearing, which finally changes the pressure waves of sound into nerve impulses The central bony support of the cochlea is called the modiolus A thin bony plate, called the spiral lamina, extends from the modiolus and partially divides the cochlea The division is completed by the basilar membrane, which is the fibrous support for the organ of Corti One passageway above the divider begins at the oval window, or scala vestibuli Another begins at the round window, or scala tympani They are joined at the apex, or helicotrema Between the two is the scala media, or cochlear duct, which contains the organ of Corti When extended the cochlea is about one and a third inches (35 mm) long It has two and three quarter turns and is about 5 mm high and 9 mm in diameter adj: cochlear See also: ORGAN OF CORTI
A snail-shaped structure in the inner ear, which is the essential organ of hearing This tube is filled with tiny hair cells, which help transmit sound into the brain
shaped like a snail's shell, this organ of the inner ear contains the organ of Corti, from which the eighth nerve fibers send electric impluses, hearing signals, to the brain
A component of the inner ear with a snail shell-like structure It serves as the body's microphone, converting sound pressure from the outer ear to electrical impulses which are sent to the brain
A snail shaped organ located in the inner ear It is lined with a membrane containing thousands of feathery hair cells tuned to vibrate to different sound frequencies
The snail-shaped structure in the inner ear containing the organ of hearing Problems in this area may include nerve cells that are missing and damage to the nerve cells and balance mechanism

[ 'kO-klE-&, 'kä-klE- ] (noun.) 1688. New Latin, from Latin, snail, snail shell, from Greek kochlias, from kochlos snail; probably akin to Greek konchE mussel.
