The Science Of Nail Growth: How Your Body Creates Fingernails

Fingernails are protective plates that are found at the tips of the digits of all primates. They are made of a tough rigid protein called alpha-keratin, which is also found in the claws, hooves, and horns of vertebrates. The nail consists of the nail plate, the nail matrix, and the nail bed below it. The nail matrix is the active tissue that generates cells, which harden as they move outward from the nail root to the nail plate.

Keratin cells harden as they move outward

The nail is a protective plate characteristically found at the tip of the digits (fingers and toes) of all primates, corresponding to the claws in other tetrapod animals. Fingernails and toenails are made of a tough rigid protein called alpha-keratin, a polymer also found in the claws, hooves, and horns of vertebrates. The nail consists of the nail plate, the nail matrix, and the nail bed below it, and the grooves surrounding it. The nail matrix is the active tissue (or germinal matrix) that generates cells.

Keratin is a tissue type that has amino acid proteins. Keratin is naturally present in your hair and nails. It’s also a component found in other animals, including horse hooves. The way keratin cells link to form together can influence the consistency and feel of the fingernails. For example, the nail layers are made of soft, moderately hard, and hard keratin. These all come together to create the protective shield you know as your fingernails. While the keratin cells are no longer living (which is why you can trim your fingernails and toe nails), they represent formerly living cells that needed nutrients and proteins to survive.

The nail root (or sinus) is located a couple of millimetres behind the cuticle of your finger and toe nails. Bones are made up of collagen and calcium phosphate, whereas nails are made from keratin. The nail is firmly attached to the nail bed beneath it. The nail and nail bed separate at the tip of the finger or toe, where the end of the nail sticks out. This allows us to use our nails as tools, for example for scratching. The nails are also an important part of the sense of touch. The nail is framed by the lateral nail folds on the left and right side of it. The skin bordering the lower end of the nail is called the proximal nail fold. A thin layer of skin, known as the cuticle, grows over the nail there.

Nail matrix produces nail plate cells

The nail matrix is the active tissue that generates cells that become the nail plate. The nail matrix is also known as the matrix unguis, keratogenous membrane, or onychostroma. It is the part of the nail bed that is beneath the nail and contains nerves, lymph, and blood vessels. The width and thickness of the nail plate is determined by the size, length, and thickness of the matrix, while the shape of the fingertip bone determines if the nail plate is flat, arched, or hooked. The nail matrix will continue to produce cells as long as it receives nutrition and remains in a healthy condition.

The nail is made up of several different parts, including the nail plate, nail bed, cuticle and matrix. The nail is made from keratin, a tough rigid protein also found in horse hooves. The nail layers are made of soft, moderately hard, and hard keratin. These all come together to create the protective shield you know as your fingernails.

Fingernails comprise three layers of tissue called keratin. Keratin is a tissue type that has amino acid proteins. Keratin is naturally present in your hair and nails. It’s also a component found in other animals, including horse hooves. The way keratin cells link to form together can influence the consistency and feel of the fingernails. For example, the nail layers are made of soft, moderately hard, and hard keratin. These all come together to create the protective shield you know as your fingernails. While the keratin cells are no longer living (which is why you can trim your fingernails and toenails), they represent formerly living cells that needed nutrients and proteins to survive.

Nails grow around 3.5mm per month

Nails are made of a tough rigid protein called alpha-keratin, a polymer also found in the claws, hooves, and horns of vertebrates.

The cells harden as they move outward from the nail root to the nail plate.

The nail root (or sinus) is located a couple of millimetres behind the cuticle of your finger and toenails. Nails grow around 3.5mm per month, with toe nails growing 1.6mm per month. The nail plate is the part of the nail that is visible. The nail bed is the part of the nail that is attached to the nail bed beneath it. The nail and nail bed separate at the tip of the finger or toe, where the end of the nail sticks out. This allows us to use our nails as tools, for example for scratching. The nails are also an important part of the sense of touch.

Hair and nails rely on oxygenated blood flow to grow. So, very soon after death, the cells responsible for their growth will die. This grisly myth mainly comes from the illusion created when dehydrated scalp and fingertips shrink back to reveal ‘longer’ hair and nails. Nails may be dead, but they’re linked up to your blood and bones.
