What is another commonly used term for skin?

The term "integument" is widely used to refer to the skin, which serves as the body's largest organ and acts as a protective barrier. In anatomy, the integumentary system comprises not only the skin itself but also related structures such as hair, nails, and glands. The term emphasizes the skin's general function of covering and protecting the underlying tissues and organs.

"Dermis" refers specifically to a deeper layer of the skin located beneath the epidermis, and while it is an essential part of the skin structure, it does not encapsulate the whole organ like "integument" does. The "surface layer" is a vague term that could refer to the outermost part of the skin but doesn’t appropriately convey the entirety of the skin as an organ. "Cuticle" specifically refers to a thin layer of dead skin found at the base of nails and is not a general term for skin. Thus, "integument" is the most accurate term related to skin as a whole.
