- Cochlear Fluids Picture Guide
This figure shows the location of the cochlea with respect to the external ear canal. The cochlea is shown here as the blue spiral structure, which resembles a snail. (The word cochlea is derived from the Latin word for a snail shell) The cochlea is responsible for converting sounds which enter the ear canal, from mechanical vibrations into electrical signals. This process, known as transduction, is performed by specialized sensory cells within the cochlea. The electrical signals, which code the sound's characteristics, are carried to the brain by the auditory nerve.

Cochlear Implants
By Joan Laughton. A cochlear implant prosthesis is a device that includes an external package (microphone and speech processor) worn by the user and an internal package (an array of electrodes that is surgically implanted into the cochlea (end organ of hearing) in the inner ear. The internal and external components of the cochlear implant are connected via an electric coupling. Cochlear implant prostheses are designed to create hearing sensation by direct electrical stimulation of auditory neurons (nerves).
