Artificial body parts, also known as prosthetics, are devices used to replace or supplement a missing or impaired body part. Prosthetics are designed to restore the function of the missing body part and can be made from a variety of materials, including metal, plastic, and silicone. They are typically custom-made for the individual and can range from simple devices such as artificial limbs to more complex devices such as cochlear implants. Prosthetics can help improve quality of life for those with disabilities or impairments, allowing them to live more independently.
