Oct 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.

Mar 4, 2024 · The cochlea is a critical component of the inner ear in mammals, including humans, playing a vital role in the process of hearing by converting sound vibrations into electrical signals that the brain can interpret. Structure The cochlea is a spiral-shaped, conical structure resembling a snail shell, typically making 2.5 turns around its central axis,

The spiral shape of the cochlea is necessary for the transduction of different sound frequencies. The cochlea is approximately 10 millimeters (mm) wide. If it were uncoiled, the cochlea would be approximately 35 mm long.
Sound waves are funneled into the ear and strike the eardrum (tympanic membrane), resulting in vibration. These vibrations travel to the ossicles—the tiny bones located within the middle ear called the malleus, incus, and stapes. The stapes strikes the oval window, and vibrations are further conducted through the perilymph (fluid) located inside of...
The cochlea is a fluid-filled, spiral-shaped cavity found in the inner ear. It plays an important role in the function of hearing. Conditions associated with the cochlea include sensorineural hearing loss, acoustic neuroma, and tinnitus. Healthcare providers can assess the health of the cochlea by using tuning fork tests, auditory brainstem respons...
The cochlea (pl.: cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window) to the apex (the top or center of the spiral). The spiral canal of the cochlea is a section of the bony labyrinth of the inner ear that is approximately 30 mm long and makes 2 3⁄4 turns ...
Apr 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. The spiral configuration of the cochlea allows for differing frequencies to stimulate specific areas ...

The cochlea (cochleae in plural) is a hollow spiralled conical chamber of bone that propagates auditory waves from the base of the ear to the top. The spiral canal of the cochlea that surrounds the modiolus is about 30mm long. The cochlea consists of the following structures: Vestibular duct: Also known as scala vestibuli, they lie on the upper ...

Sep 10, 2024 · Human 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. It forms a cone approximately 9 mm (0.35 inch) in diameter at its base ...
