COCHLEAR IMPLANTS Meaning and
Definition
-
Cochlear implants are electronic medical devices designed to provide hearing capabilities to individuals with severe to profound hearing loss. These devices consist of two main components: an external portion and an internal portion. The external component includes a microphone that picks up sound signals from the environment and processes them into digital data. This data is then transmitted to the internal component, which is surgically implanted into the individual's cochlea, a spiral-shaped, fluid-filled structure in the inner ear responsible for converting sound vibrations into electrical signals.
The internal component of the cochlear implant system consists of an electrode array that stimulates the auditory nerve fibers within the cochlea. By bypassing the damaged or non-functional hair cells in the cochlea, the electrical stimulation from the implant is able to directly activate the auditory nerve and transmit sound information to the brain for processing and interpretation.
Cochlear implants enable individuals with severe hearing loss or complete deafness to perceive sound, which can significantly improve their ability to communicate and interact with the world around them. They are particularly beneficial for individuals who do not receive substantial benefit from hearing aids, as cochlear implants can provide more direct auditory input.
However, it is important to note that cochlear implants do not fully restore normal hearing. The quality and clarity of sound experienced with a cochlear implant may vary among individuals, and some individuals may require auditory therapy and rehabilitation to maximize their benefit from the implant.

Etymology of COCHLEAR IMPLANTS
The word "cochlear implants" originates from the combination of two terms: "cochlear" and "implants".
1. Cochlear: The term "cochlear" derives from the Latin word "cochlea", which means "snail" or "spiral shell". The cochlea is the snail-shaped, fluid-filled structure in the inner ear responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.
2. Implants: "Implants" comes from the Latin word "implantare", which means "to graft" or "to plant". In this context, it refers to the surgical procedure of implanting an artificial device into the ear to restore hearing capability.
Therefore, "cochlear implants" refers to the medical device that is surgically inserted into the cochlea to help individuals with severe hearing loss or deafness regain auditory sensation.
