Why are nails part of the integumentary system?




Nails, which are modifications of the epidermis, are protective coverings on the ends of the fingers and toes. Each nail consists of a nail plate that overlies a surface of skin called the nail bed. The whitish, thickened, half-moon shaped region (lunula) at the base of the nail plate is the most actively growing region. Nails, like
hair, are primarily dead keratinized cells.
