Fingernail
The fingernail (nail plate) corresponds to stratum corneum and rests on a nail bed of strata basale and spinosum. The nail root lies in an epidermal fold, whose stratum corneum forms the eponychium (cuticle). Beneath the root is the nail matrix, the germinative portion of the nail. The hyponychium, a thickened epidermis, secures the nail at the fingertip. Upper 4x; Lower 20x
