NEET PG DENTAL EXAM

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: -Nail root: The root of the nail is also known as the germinal matrix. Its edge appears as a white crescent, known as the lunula. The root portion of this nail lies below the skin, underneath the nail, and extends several millimeters into the finger. It produces most of the volume of the nail and the nail bed.

Detailed explanation-3: -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. Fingernails grow at a rate of about 3 millimeters per month. Toenails grow a little slower.
