nail structure Flashcards
the mantle
a pocket-like structure that holds the root matrix
the nail matrix
active tissue that generates cells, which harden as they move outward to form the nail plate
the nail root
it is attached to the matrix at the base of the nail, under the skin and inside the mantle
the nail bed
the area of the nail where the nail body rests, nerves, and blood vessels found here supply nourishment
the nail plate
the visible nail area from the nail root to the free edge
the lunula
half moon shaped at the base of the nail, which is the visible part of the matrix and appears lighter
the eponychium
the live tissue at the base of the nail
the cuticle
the overlapping dead tissue that is loose and pliable around the nail
the nail grooves
the tracks on either side of the nail that the nail moves on as it grows
the sidewalls
the folds of skin on either side of the nail groove
the perionychium
the living tissue that overlies the nail plate on the sides of the nail
