the part of the ear, filled with fluid, which contains the cannals which are the primary sensors for change in the position of the head.

The part of the ear where vibrations are changed into the signal that is carried to the brain, which is experienced as sound. It consists of a complicated series of channels and chambers, including the semicircular canals (organ of balance) and the cochlea (organ of hearing).

See internal ear.

made up of delicate and complex passages that include the semicircular canals and the cochlea

That part of the ear, particularly the cochlea, that converts mechanical vibrations (sound) into neural messages that are sent to the brain.

The innermost section of the ear. It contains the cochlea, semicircular canals, saccule, and utricle.

the part of the ear in the temporal bone consisting of the semicircular canal, vestibule and cochlea. It is contained within a system of spaces and canals, known as the osseous or bony labyrinth, in the temporal bone. These spaces and canals are divided into three sections: the vestibule, which contains two balance organs, the utricle and saccule; the semicircular canals, and the cochlea.

the portion of the ear, beginning at the oval window, which transmits electric impluses, sound signals, to the brain. It helps maintain balance. It consists of the cochlea and vestibular apparatus.

The cochlea. (See Cochlea).

a complex system of interconnecting cavities; concerned with hearing and equilibrium

The inner ear (or labyrinth) is a convoluted system of cavities and ducts comprising the organs of hearing and balance.

Cochlea, semicircular canals and auditory nerve.

the innermost part of the ear where sound information is sent to the brain through the acoustic nerve.

inside the ear is a coiled tubed called the cochlea; the cochlea is filled with fluid and nerve endings

the sensory organs of hearing (cochlea) and balance (vestibular canals) located within the temporal bone.

The section of the ear that encompasses the cochlea, hair cells and hearing nerve to the brain. If a person has a sensorineural hearing loss, the problem occurs in the inner ear.

The portion of the ear that includes the cochlea and the semi-circular canals. These structures are responsible for the sense of hearing, balance, motion, etc.

part of the ear that contains both the organ of hearing (cochlea) and the organ of balance (labyrinth).

The anatomical portion of the hearing system that triggers nerve impulses that travel to the brain. Both the hearing and balance systems are found in the inner ear. The cochlea is a small snail-shaped structure that contains the tiny hair cells that sense sound and send signals to the auditory nerve. The semicircular canals sense balance and position changes and report these changes to the brain.

part of the ear that contains the cochlea, an organ of hearing, and the labyrinth, an organ of balance

The cochlea. The snail-like portion of the ear system that converts mechanical sound energy coming from the middle ear into an electrical impulse prior to transmission to the brain.

The concave (curved inward) portion of the ear.

The portion of the ear in which the actual transduction of sound takes place.

The most interior portion of the ear, made up of two interconnected parts: the vestibular system, a balance organ, and the cochlea, a hearing organ.

That portion of the ear which lies inward from the middle ear, and which is comprised of the cochlea, containing the organ of Corti. The inner ear also includes the Vestibular (balance) system.

Consists of a complex cavitation in the temporal bone and is divisible into three parts, the vestibule (in the middle), cochlea (in front), and semicircular canals (in the back). All three parts form a continuous and tortuous cavitation which is lined loosely by a membrane ( membranous labyrinth) separated from the bone surface by a fluid called perilymph. The membranous labyrinth, like most linings of the body, is in substance a sac with intricate ramifications. Its cavity contains a fluid called endolymph. The hearing portion of the labyrinth is the cochlea. The balance portion consists of the vestibular endorgans.

Includes the semicircular canals, the cochlea, and the auditory nerve. Problems in this part of the ear may include damaged or missing nerve cells and damage to the balance mechanism.

The portion of the ear containing the nerve endings critical to hearing

The inner ear is a labyrinth of twisting fluid-filled passages associated with hearing and balance. Three canals wind into a snail-shaped structure called the cochlea. Sound vibrations amplified by the bones of the middle ear travel through these canals, which in turn causes tiny hairs to to move. When these hairs rub against each other they push on protein molecules protruding from the surfaces of each hair. The molecule then acts as a lever, opening a channel, known as an ion gate, inside the hair and so allowing potassium ions to flow from the top of the hair into the cells at its root. This flow of ions triggers an electrical signal which the brain interprets as sound. At the base of each level is a molecular spring which returns the lever to its original position, ready to detect the next vibration. Sounds from the outside are in this way encoded to travel to the brain. The rear section of the inner ear houses the semicircular canals. Connected to each other by the structure called the vestibule, the canals are sensitive to gravity, acceleration, and head movement and position.
