PATHOLOGY

Detailed explanation-1: -Fingernails and toenails are made from skin cells. Structures that are made from skin cells are called skin appendages. Hairs are also skin appendages. The part that we call the nail is technically known as the “nail plate .” The nail plate is mostly made of a hard substance called keratin.

Detailed explanation-2: -Background: Keratin, an alpha-helical fibrous protein, is the primary component of human nail plates. No data on age-related changes in healthy subjects are present.

Detailed explanation-3: -Fingernails and toenails are made of a tough protective protein called alpha-keratin, which is a polymer.

Detailed explanation-4: -Keratinocytes (pronounced: ker-uh-TIH-no-sites) make keratin, a type of protein that’s a basic component of hair, skin, and nails. Keratin in the skin’s outer layer helps create a protective barrier.
