- The cochlea is the sense organ that translates sound into nerve impulses to be sent to the brain. Each person has two cochlea, one for each ear. The cochlea is a fluid-filled, snail shaped cavern in the mastoid bone of your skull behind each ear. Tiny bones in the middle ear transmit sound from the eardrum across the middle ear and vibrate against the cochlea.

Headphones Headphones are designed to allow a single user to listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air, allowing anyone nearby to listen. Headphones are also known as earspeakers, earphones or, colloquially, cans. Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place. The other type, known as earbuds or earphones consist of individual units that plug into the user's ear canal.

Organ of Corti The organ of Corti, or spiral organ, is the receptor organ for hearing and is located in the mammalian cochlea. Described as a masterpiece of cellular micro-architecture, this highly varied strip of epithelial cells allows for transduction of auditory signals into nerve impulses' action potential.

The Inner Ear The inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph). The Organ of Corti is the sensory receptor inside the cochlea which holds the hair cells, the nerve receptors for hearing.

Cochlear Implants Cochlear Implants. A cochlear implant is an electronic device that restores partial hearing to individuals with severe to profound hearing loss who do not benefit from a conventional hearing aid. It is surgically implanted in the inner ear and activated by a device worn outside the ear.

- Quick Answer. The cochlea is the auditory center of the inner ear, a fluid-filled organ that translates the vibrations of auditory sound into impulses the brain can understand. This occurs at the organ of Corti, a structure consisting of tiny hairs throughout the cochlea that vibrate and send electrical signals through the nervous system. Continue Reading

Ear Organ of Corti. (inside cochlea) organ located in the cochlea; contains receptors (hair cells) that receive vibrations and generate nerve impulses for hearing. -------sense organ of hearing; runs along length of basilar membrane; consists of hair and support cells that react to the traveling wave.

âââââââââââââââââââââââââââââââââââââââââââââââââââââThere are three anatomical regions of the ear - the outer ear, middle ear and inner ear. Each region of the ear contains structures that play a vital role in your hearing and balance. The cochlea is the inner ear organ of hearing. The cochlea is lined by thousands of very small nerve endings. When sound waves cause the fluids in the cochlea to move, it activates the nerve endings. There are many causes of cochlear hearing loss. Some patients benefit from a hearing aid.

A to Z List of Neurological Disorders Epilepsy is not a very common disease compared to some other neurological diseases (e.g. like migraine). At any one time, less than one percent of Americans suffer from epilepsy. The lifetime risk of one having a defined epilepsy is probably on the order of about 5%. The incidence of epilepsy (the number of new cases per population per year) is relatively high during the first few years of life. Risk factors for the development of childhood seizures include: 1  Infection of the central nervous system. 2  Mental retardation.

Auditory Nerve The Auditory Nerve, also known as the Cochlear or acoustic nerve (part of the vestibulocochlear or 8th cranial nerve), is a sensory nerve, it is found in the head and transmits information from the inner ear (cochlea) to the brain in the form of sound (acoustic) energy that impinges on the ear drum (tympanic membrane).he Auditory Nerve, also known as the Cochlear or acoustic nerve (part of the vestibulocochlear or 8th cranial nerve), is a sensory nerve, it is found in the head and transmits information from the inner ear (cochlea) to the brain in the form of sound (acoustic) energy that impinges on the ear drum (tympanic membrane).

Picture of the Ear The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that travel to the brain. The fluid-filled semicircular canals (labyrinth) attach to the cochlea and nerves in the inner ear. They send information on balance and head position to the brain.

- A specialized structure located on the inner surface of the basilar membrane of the cochlea containing hair cells that transmit sound vibrations to the nerve fibers.

- A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing.Cochlear implants may help provide hearing in patients who are deaf because of damage to sensory hair cells in their cochleas.These sensory cells unlike most of the other cells in the body, never regenerate. Thus, the hair cells are irreplaceable in any matter. There are 4 manufacturers for cochlear implants, and each one produces a different implant with a different number of electrodes. 2  The number of channels is not the sole basis upon which a manufacturer is chosen; the signal processing algorithm is another important consideration.

Auricle Human ear, organ of hearing and equilibrium that detects and analyzes noises by transduction (or the conversion of sound waves into electrochemical impulses) and maintains the sense of balance (equilibrium).

Vestibulocochlear nerve The vestibulocochlear nerve is responsible for both hearing and balance and brings information from the inner ear to the brain. A human's sense of equilibrium is determined by this nerve. Two special organs help the nerve function properly: the cochlea and the vestibular apparatus.

What is the Vestibulocochlear Nerve? The vestibulocochlear nerve is a sensory nerve that conducts auditory and vestibular information from the inner ear to the brain.Auditory functions manage hearing, while vestibular functions serve to maintain balance and awareness of the body's position.nce referred to as the auditory or acoustic nerve, the vestibulocochlear nerve begins in the medulla oblongata, or the lower portion of the brain stem. It then travels alongside the facial nerve and enters the inner ear through the internal acoustic meatus, a hole in the temporal bone of the skull.

The Inner Ear The inner ear contains the sensory organs for hearing and balance. The cochlea is the hearing part of the inner ear. The semicircular canals in the inner ear are part of our balance system. The cochlea is a bony structure shaped like a snail and filled with two fluids (endolymph and perilymph). The Organ of Corti is the sensory receptor inside the cochlea which holds the hair cells, the nerve receptors for hearing. The mechanical energy from movement of the middle ear bones pushes in a membrane (the oval window) in the cochlea. This force moves the cochlea's fluids that, in turn, stimulate tiny hair cells.

These structures help control one’s sense of steadiness or balance. These balance organs share the temporal bone space with the cochlea. These organs also share the same fluid that is in the cochlea.

Vestibulocochlear nerve This is the nerve along which the sensory cells (the hair cells) of the inner ear transmit information to the brain. It consists of the cochlear nerve, carrying information about hearing, and the vestibular nerve, carrying information about balance.he vestibulocochlear nerve (auditory vestibular nerve) , known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.
