A small, snail-shaped organ of the inner ear in which the energy of sound is converted into electrical energy for transmission to the brain.
A spiral tube inside the inner ear, which is the essential organ of hearing.
A fluid-filled, snail-shaped, bony shell in the inner ear, which contains the organ of Corti, the actual organ of hearing; problems in the cochlea can lead to significant ear and hearing problems.
Snail-shaped part of the inner ear whose sensory cells are stimulated by sound waves during hearing.
A coiled structure located in the inner ear that is shaped like a snail shell and contains the organ of corti.
A membranous space inside the cochlea that surrounds the organ of corti.
The fluid-filled, snail-shaped structure in the inner ear that translates sounds into electrical impulses and relays them to the brain. Sound waves that reach the inner ear vibrate a membrane called the oval window, which transmits the sound waves into the fluid environment within the cochlea. In the cochlea is a structure called the organ of Corti, which contains millions of tiny hair cells and acts as an analyzer of the frequency of sound waves. The movement of the fluid stimulates the hair cells. Higher pitched tones maximally stimulate the hair cells at the base of the cochlea, and lower pitched sounds stimulate the hair cells at the farther end. The bending of the hair cells converts pitch and volume information into nerve impulses that are transmitted via the eighth cranial nerve to the auditory cortex, the area of the brain where sound is perceived and interpreted.
The spiral organ of the labyrinth of the ear, which is concerned with the reception and analysis of sound. As vibrations pass from the middle ear through the cochlea, different frequencies cause particular regions of the basilar membrane to vibrate: high notes cause vibration in the region nearest the middle ear; low notes cause vibration in the region nearest the tip of the spiral. The organ of Corti, which lies within a central triangular membrane-bound canal (scala media or cochlear duct), contains sensory hair cells attached to an overlying tectorial membrane. When the basilar membrane vibrates the sensory cells become distorted and send nerve impulses to the brain via the cochlear nerve.
A winding cone-shaped tube forming a portion of the bony labyrinth of the inner ear. It contains the organ of Corti, the receptor for hearing.
A coiled, fluid-filled tube that is found in the inner ear and that is involved in hearing.
The auditory component housed within the inner ear, known as the cochlea, exhibits a distinctive spiral shape and encompasses fluid-filled chambers along with numerous minuscule hair cells that are finely attuned to different frequencies.
The cochlea, a spiral-shaped organ located within the labyrinth of the inner ear, plays a crucial role in the sense of hearing. Contained within the cochlea is a structure called the organ of Corti, which is responsible for detecting sound vibrations of varying frequencies and converting them into electrical signals. These electrical impulses are then transmitted to the brain through the vestibulocochlear nerve. Different regions inside the cochlea are stimulated by sound waves of different frequencies, allowing us to perceive and distinguish a wide range of sounds.
The tiny, snail shell-shaped structure that serves as the essential organ for hearing.
