FAQ
Frequently Asked Questions
No. The eardrum (tympanic membrane) is in the middle ear and vibrates in response to sound. The cochlea is a fluid-filled, spiral-shaped structure in the inner ear that converts those vibrations into electrical signals.
A cochlear implant is a surgically implanted electronic device that bypasses damaged parts of the inner ear (cochlea) and directly stimulates the auditory nerve to provide a sense of sound to a person with severe hearing loss.
In humans, the delicate hair cells inside the cochlea do not regenerate naturally if they are destroyed, which is why most sensorineural hearing loss is permanent. This is a major focus of medical research.
The spiral, snail-shell shape allows a long, frequency-sensitive membrane (the basilar membrane) to be packed into a small space. Different parts of this membrane resonate to different sound frequencies.

Memory Aids
Mnemonic
Think of a COIL or a snail's SHELL. The word 'cochlea' comes from Latin for 'snail shell', and it has the same spiral shape.
Conceptual Metaphor
The cochlea is often metaphorically described as a "spiral staircase" for sound waves or a "biological microphone" converting vibrations into signals.
