The developmental origins of nails, hair, and glands. Concept introduction: The integumentary system covers the outer surface of the skin. The specialized structure of this system includes hair, nails, sweat glands, mammary glands, and teeth. The integument or integumentary system is derived from the ectoderm and mesoderm germ cell. The ectoderm is originated from the epidermis, whereas the mesoderm is originated from the dermis layer of skin.
