NEET PG DENTAL EXAM

Detailed explanation-1: -Fingernails and toenails are made of a tough protective protein called alpha-keratin, which is a polymer. Alpha-keratin is found in the hooves, claws, and horns of vertebrates.

Detailed explanation-2: -Most of us do know that nails are made of a tough, dead substance called keratin, the same material that makes up hair. But nails actually start out as living cells. Behind the cuticles on fingers and toes, just beneath the skin, a structure called the “root” churns out living cells that go on to form the nail.

Detailed explanation-3: -Nail plates contain 80–90% hard keratins and the remaining part is soft. The -keratins are also primary constituents of hair and the stratum corneum of skin.
