GENERAL HISTOLOGY

Detailed explanation-1: -Nails start in the nail root, hidden under the cuticle. When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells. The newly formed nail then slides along the nail bed, the flat surface under your nails.

Detailed explanation-2: -Nails look as if they grow only from the tips of the fingers or toes and this is the portion, which we cut or trim. But in fact, nails start growing from the nail bed, a small surface that is just below where your nail disappears into your fingers or toes.

Detailed explanation-3: -The nail root is the portion of the nail found under the surface of the skin at the near (or proximal) end of the nail. It is where the nail begins. The nail plate (or body) is the portion of the nail that is external to the skin. It is the visible part of the nail.

Detailed explanation-4: -This is the visible part of the matrix. It is called the lunula (Latin for “small moon”) because of its shape. The matrix constantly produces new keratin that gathers at the nail plate and slowly pushes the nail forward, causing it to grow.
