neglematriks
Neglematriks, or the nail matrix, is the tissue at the base of the nail responsible for the production of the nail plate. It lies beneath the proximal nail fold and extends distally under the nail root; the lunula marks the visible part of the matrix through the translucent nail plate. The matrix consists of living epidermal cells that proliferate and keratinize to form hard keratin, which becomes the nail plate as it grows outward over the nail bed.
Growth and anatomy: The matrix generates the nail plate continuously, with fingernails growing roughly 2–3 millimeters
Clinical significance: Injury or disease affecting the matrix can cause permanent or temporary nail dystrophy. Changes
Related conditions: Onychomatricoma is a rare tumor of the nail matrix. Matrix involvement is also relevant
