The nail bed
The only living part of the nail is the Matrix which is situated just below the cuticle.
The nail plate is produced by living skin cells ( specialized epithelial cells)
i belive it is the nail root.
They are composed of a protein called keratin.
Abiotic means without life and these are made of dead cells growing from a nail bed of living cells.
The nail bed is primarily composed of specialized epidermis. It lies beneath the nail plate and contains living cells that contribute to nail growth. The nail bed is rich in blood vessels and nerve endings, which provide nutrients and sensation but is technically part of the epidermal layer.
Nails grow by mitosis of cells in the stratum germinativum beneath the lunula (it looks like part of the noon) on the nail bed; average growth is about 0.5 mm per week, or slightly over 1 inch per year.
Yes, your entire body is made up of cells both dead and alive.
Just like hair, your nails are protein deposits that grow as needed. They have no blood cells or veins to feed them, so they are not living.
Living skin cells in the finger are what produced fingernails. A fingernail is made of several parts. The nail plate, the nail bed, the cuticle, the nail folds, the lunula, and the matrix are all parts of the fingernail. Nails grow from the matrix and are composed of keratin. When new cells grow, the older cells are pushed out.
Nails are made up of keratin, a protein that is produced by specialized cells in the nail matrix. While nails themselves do not have living cells, the nail matrix located underneath the base of the nail is where nail growth occurs.
The white, half-moon shape at the base of your nail is called the lunula. It is a visible part of the nail matrix where new nail cells are produced.
