Nails are additional organs in the skin that cover the tips of the fingers, and in many times the nails are the health indicator of your body, so what are the nails and how are their formation and the most important health functions? Follow this article with us, we will list the most important information about nails and everything related to them.
What are nails?
Nails are a strong outer layer that covers the tip and front of the fingers, as it covers the five fingers of each hand and foot in the human body, and it is the part that is synonymous with the hoof or claw in other vertebrate organisms.
Nail shape and composition
The nail is a horn-shaped layer or plate, about half a millimeter thick. The main component of the nail is the tough protein keratin. The production and formation of the nail is through the living skin cells present in the fingers, and the nails generally consist of 4 different parts, and they are as follows:
- nail plate Or the nail plate, which is the outer layer or the visible outer part of the nail, which is a solid part consisting of layers of dead cells.
- nail bed Or the nail bed, which is the layer that covers and spreads under the nail plate and serves as the lining. This part is thin skin like cuticle with a layer of blood vessels and is light pink in healthy people.
- nail matrix or the vertices of the matrix, which are grooves that connect the nail bed to the skin plate. This part is the base of the nail. It contains blood vessels and nerves that lead to the emergence of the cells of the nail plate at the root part of the nail.
- The last area under the nailIt is the part of the skin that is located below the edge of the nail in the free area that is not connected to the nail bed, as this layer is located behind the end of the nail bed, and is considered a barrier to germs and other harmful things.
As the nail grows, the new cells of the nail plate that develop at the root of the nail push the old cells forward, causing them to push up at the front of the nail plate.
Old cells, when pushed up and pressed, become more transparent than when they were near the root. They become stiff, flat, flattened, and appear in the familiar shape of nails. They also become more flattened.
Many times a small, white, crescent-shaped part appears at the base of the nail root. This part is part of the nail matrix and is known as the moon or little moon. This crescent is a protective layer made up of dead cells. This layer covers the nail plate from the back.
nail growth rate
Many wonder about the normal rate of nail growth in the body, so we explain to you that the average natural growth rate of the nail is 0.1 millimeter per day, equivalent to 1 cm every 100 days. This percentage varies slightly from one individual to another, because there are a number of factors that affect this rate of growth, such as:
- person’s age.
- the person’s gender.
- timing of the year.
For example, nail growth is faster and at a higher rate among young people, especially males, during the summer. Also, fingernails grow faster than toes. The nail of the hand takes about 6 months to grow from the root to the tip, while the toenail takes about 12 to 18 months to grow from the root to the tip.
In addition, the nails of the right hand grow faster than the left hand. There are some conditions that affect nail growth rates, including:
