COCHLEAR IMPLANT Meaning and
Definition
-
A cochlear implant refers to a medical device designed to restore or enhance hearing abilities in individuals with severe to profound hearing loss or deafness. It serves as a prosthetic replacement for the damaged or nonfunctioning inner ear structure called the cochlea. The implant stimulates the auditory nerve directly to transmit sound signals to the brain, bypassing the damaged portion of the ear.
The cochlear implant consists of two main components - an external speech processor and an internal receiver-stimulator. The speech processor captures and analyzes sound information from the environment, converting it into digital signals. These signals are then sent to the internal receiver, which is surgically implanted beneath the skin behind the ear. The receiver sends electrical currents to an array of electrodes placed within the cochlea, stimulating the auditory nerve fibers responsible for transmitting sound information to the brain.
The brain interprets these electrical signals as sound, allowing individuals with cochlear implants to perceive speech, environmental sounds, and other auditory cues. However, it is important to note that the sound perception with a cochlear implant differs from that of normal hearing.
Cochlear implants have proven to be highly effective in providing a sense of sound and promoting speech understanding, especially in children who receive them at an early age. They have transformed the lives of many individuals with profound hearing loss, enabling them to communicate, enhance their social interactions, and improve their overall quality of life.

Etymology of COCHLEAR IMPLANT
The word "cochlear implant" has its roots in two different Latin words.
1. "Cochlear" comes from the Latin word "cochlea", which means "snail". The term was originally used to refer to the spiral-shaped structure that resembles a snail shell found in the inner ear. The cochlea is responsible for converting sound vibrations into electrical signals that can be perceived by the brain.
2. "Implant" derives from the Latin word "implantare", which means "to plant" or "to fix in place". In the context of medical terminology, an implant refers to a device or object that is surgically inserted or attached to a specific part of the body to replace or enhance its original functionality.
