What is the term for a device used to take the place of a missing body part?

Orthotic
Prosthesis
Supportive device
Assistive technology

The correct answer is: Prosthesis

The term for a device used to take the place of a missing body part is "prosthesis." This term specifically refers to artificial devices that are designed to replace a missing limb or body part, such as a leg or an arm. Prostheses are crafted to fit the individual's needs and are often custom-made to ensure comfort and functionality, allowing the person to regain mobility or functionality that may have been lost due to injury, congenital conditions, or amputation. While supportive devices, orthotics, and assistive technology serve important roles in healthcare and rehabilitation, they do not fit the exact description of replacing a missing body part. Supportive devices may provide stability or aid for existing limbs, orthotics are typically used to support or correct the function of a body part without replacing it, and assistive technology encompasses a broader range of tools designed to help with daily tasks but does not specifically designate devices that replace missing anatomy.
