What is the Latin term used for nails?

The Latin term used for nails is "Onyx." This term specifically refers to the hard, keratinized structure that forms the visible part of the nail. The word "onyx" has its roots in the Ancient Greek word meaning "fingernail" or "claw," and it is commonly used in both medical and beauty contexts to describe the nail itself.

The other terms listed have distinct meanings related to nail anatomy or skin biology but do not refer directly to nails. For instance, "eponychium" refers to the tissue that overlaps the base of the nail, while "dermis" is a layer of skin beneath the epidermis, and "stratum" generally refers to layers of skin or tissues. Understanding these specific terms helps clarify the unique role each component plays in nail and skin health.
