The main organ of the inner ear, responsible for the initial analysis of sound waveforms.

A fluid-filled tube that curls into a snail-like shape. The cochlea contains the basilar membrane, which in turn contains auditory receptor cells called hair cells. These transduce the mechanical energy of the sound wave into neural impulses. go to glossary index

The cochlea is part of the inner ear. It is a spiral tube about 3.5 centimetres long which coils 2.7 times. When sound waves enter the cochlea, hair cells trigger an electrical pulse in the auditory nerve. Different frequencies of sound are picked up by different hair cells, depending on where in the spiral tube they are located. The nerve passes electrical impulses to your brain, which recognises them as different sounds, for example people talking or footsteps.

a winding, cone-shaped tube forming a portion of the inner ear and containing the spiral organ (organ of Corti)

The portion of the inner ear that senses sound.

the part of the inner ear containing the sensory mechanism of hearing.

the organ in the inner ear, devoted to hearing.

A tiny spiral shaped structure, about the size of a pea. It is nestled in the bone of the skull and filled with fluid. A thin membrane with around 15,000 tiny hair cells sits in this fluid. Each cell is tuned to a particular sound or frequency. The tiny hair cells connect to the cochlea nerve that sends messages along the auditory nerve to the brain.

Latin = snail, hence the spiral cochlea, adjective - cochlear.

a snail-like series of coiled tubes within the skull that assist hearing.

Shaped llike a snail's shell, this organ of the inner ear helps transmit hearing signals to the brain.

An organ of the inner ear that's lined with tiny hairs which are attached to nerves. The nerve bundle from the cochlea then goes to the brain for processing.

The spiral portion of the bony labyrinth of the inner ear that surrounds the organ of hearing.

is found in the inner ear and contains the receptors for hearing

The snail-like bony cavity that contains the delicate hair cells located in the inner ear. It is about the size of a dried pea.

A portion of the labyrinth associated with hearing. It is rolled in the shape of a snail shell. The organs of Corti line the cochlea.

named after the Latin word for shell, the cochlea is a coiled, tapered tube inside the inner ear which transmits sound to the Organ of Corti, the sensory organ of hearing. It is a spiral tube about 3.5cm long that coils around. The spiral contains two fluid–filled chambers. The outer chamber starts at the oval window, goes to the end of the cochlea and then doubles back to the round window. Vibrations caused by sound pass from the stapes through the oval window and into the fluid in the outer chamber. The inner central chamber of the cochlea contains the Organ of Corti, which has thousands of small ‘hairs’ along the length of the cochlea. Each hair is connected to nerve fibres that join other similar fibres to form the auditory nerve which goes from the cochlea to 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.

This hearing organ makes up the inner ear. Looking like the round shell of a snail, it is composed of a network of liquid filled tubing that also houses the tiniest of hairs. When sound is sent here by the ossicles it causes ripples in the liquid and the hairs to bend. This movement triggers electrical impulses which are transmitted to the auditory nerve. (See Auditory Nerve and Ossicles).

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

a spiral-shaped cavity of the inner ear which contains nerve endings

A coiled organ in the inner ear that plays a large role in hearing by picking up sound vibrations and transmitting them as electrical signals.

L. snail shell. The receptor organ of hearing is so-named because of its striking resemblance, with its two and a half turns, to a snail shell.

the inner ear which consists of bony and membrane chambers which contain fluids and the sensory cells (hair cells) which send sound from the middle ear to the auditory nerve. Damage to the sensory cells in the inner ear is the most common cause of permanent hearing loss. The inner ear is physically connected to the balance mechanism.

A spirally wound tube-like structure that forms part of the inner ear and is essential for hearing.

A snail-shaped, fluid-filled organ of the inner ear that contains the basilar membrane. It is responsible for translating the motion of the basilar membrane into nerve signals that lead to the perception of sound.

The snail-shaped organ in the inner ear which processes sound.

(KOK-lee-aw) The portion of the inner ear that contains the receptors of hearing (the organ of Corti).

The inner ear structure that contains the end-organ of hearing, also referred to as the inner ear.

The spiral-shaped bony canal in the inner ear containing the hair cells that transduce sound.

A hollow tube in the inner ear that is coiled to resemble a snail's shell; it contains thin fluid and the organ of Corti, and it is where sound vibrations picked up by the middle ear are carried

A spiral tube forming part of 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.

part of the inner ear involved in hearing.

A snail-shaped, fluid-filled organ of the inner ear responsible for transducing motion into neurotransmission to produce an auditory sensation.

part of the inner ear, contains fluid and hair-like nerve cells that convert mechanical energy from the middle ear into electrical impulses

The snail-shaped portion of the inner ear that contains the hair cells and nerve endings that convert a sound from the mechanical/vibratory movements present in the middle ear into an electrical charge, as the sound travels to the brain for processing.
