Cochlea: Anatomy, Function, and Treatment - Verywell Health
WebJul 6, 2022 · The cochlea is a fluid-filled, snail-like structure within a cavity in the inner ear. It plays a vital role in the function of hearing rather than simply being another component of the skeletal system. The cochlea contains hair cells that convert sound waves into electrical impulses that are carried along the auditory nerve to the brain.
Cochlea - Wikipedia
WebThe cochlea is a portion of the inner ear that looks like a snail shell (cochlea is Greek for snail). The cochlea receives sound in the form of vibrations, which cause the stereocilia to move. The stereocilia then convert these vibrations into nerve impulses which are taken up to the brain to be interpreted.

WebOct 30, 2023 · The cochlea is a component of the labyrinth of the internal ear that is responsible for hearing. It is a hollow, spirally coiled chamber inside the temporal bone that makes 2.75 turns around its axis, which is called the modiolus. The cavity of the cochlea (cochlear canal) houses a triangular membranous duct, called the cochlear duct. The ...

WebHuman ear - Cochlea, Hearing, Balance: The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turns around a hollow central pillar, the modiolus.

WebApr 1, 2023 · The cochlea is a fluid-filled, spiral-shaped cavity found in the inner ear that plays a vital role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual sound frequencies.

WebAug 16, 2023 · Cochlea: The cochlea is made of a hollow bone shaped like a snail and divided into two chambers by a membrane. The chambers are full of fluid, which vibrates when sound comes in and causes the 30,000 tiny hairs lining the membrane to vibrate and send electrical impulses (sound signals) to the brain.

WebOct 30, 2023 · The cochlea is a spirally coiled component, which terminates at the cochlear cupula. The canal makes its spirals around a bony core known as the modiolus. The cochlea contains the cochlear canal, inside which the cochlear duct rests. The latter is divided into two canals: the scapa tympani and the scala vestibuli.
How the Ear Works | Johns Hopkins Medicine
WebThe cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.
How Do We Hear? | NIDCD
WebThe bones in the middle ear amplify, or increase, the sound vibrations and send them to the cochlea, a snail-shaped structure filled with fluid, in the inner ear. An elastic partition runs from the beginning to the end of the cochlea, splitting it into an upper and lower part.
