The whitish, half-moon shape at the base of the nail is known as the lunula
the dead tissue that tightly adheres to the natural nail plate is the cuticle
the tough band of fibrous tissue that holds an organ in place consists of ligaments

Unlike healthy hair, healthy nails are not _______ periodically shed
It takes about ________ for toenails to be fully replaced 9 to 12 months
The living skin at the base of the natural nail plate covering the matrix area is the eponychium
the thin layer of tissue that attaches the nail plate and the nail bed is the bed epithelium
The slightly thickened layer of skin under the nail that lies between the fingertip and the free edge of the nail plate is the hyponychium
The dead, colorless tissue attached to the natural nail plate is known as the nail cuticle
