The nail is a(n) _________ of the skin.

• A. Accessory
• B. Appendage
• C. Organ
• D. Structure

Answer: (B)

The nail is classified as an appendage of the skin. This terminology is often used in the study of anatomy and physiology to describe structures that extend from the body, such as hair, nails, and glands. As an appendage, nails serve specific functions, including protection and enhancing the sensation of touch. The structure of nails is closely related to the epidermis, the outer layer of skin, and they develop from the nail matrix, which is situated beneath the cuticle. This relationship reinforces their status as appendages rather than standalone organs. While nails could be seen as structures, the term appendage provides a more precise and meaningful description in the context of their connection to the skin. In comparison, while the options of accessory, organ, and structure might describe certain aspects of nails, they do not encapsulate the complete relationship between nails and the skin. Accessory is too vague, an organ typically refers to a complete functional unit, and structure, while accurate, lacks the specificity that "appendage" offers in this context.
