What is the nail matrix and why is it important?
The nail matrix is the most important structure within the nail unit. This is where new nail plate cells are created and as these new cells are created, older cells are pushed forward and the nail plate grows. The shape and size of the matrix determines the thickness and width of the nail.
What is the function of the nail folds?
Nail folds – skin that surrounds and protects the proximal and lateral margins of the nail plate Nail bed (sterile matrix) – lies underneath the nail plate, attaching it to the distal phalanx. The nail bed provides a smooth surface for the growing nail plate to slide over (it does not contribute to plate growth itself).
What is the sterile matrix of the nail bed?
Nail bed (sterile matrix) – lies underneath the nail plate, attaching it to the distal phalanx. The nail bed provides a smooth surface for the growing nail plate to slide over (it does not contribute to plate growth itself). Germinal matrix – area of soft tissue proximal to the sterile matrix.
What is the germinal matrix of fingernails?
Fingertip skin is connected to the sterile matrix. Germinal matrix. This is the area of the nail below the lunula (closest to the knuckle). An estimated 90 percent of nail production comes from the germinal matrix. This gives a natural curvature to the nail.

This resulted in a permanent scar of the nail matrix, which in turn created a split in the nail plate. The only way to repair this would be to surgically remove the scar.
What is matrix in nail care?
The Matrix is the living portion found at the base of the nail. This is where new cells develop and push the old, "dead" cells forward to form the nail plate. The quality and health of these cells determine the general condition of the nail as it grows beyond the matrix.
What protects the nail bed from infection?
The nail fold consists of the germinal matrix and eponychium. Below the distal attachment of the nail with the pulp skin is the plug of keratinous mass called hyponychium, which is rich in polymorphs and lymphocytes which act as a barrier to infection.
What part of the nail that holds the nail root and Matrix?
Nail bed: The nail bed is also referred to as the sterile matrix. It extends from the edge of the nail root, or lunula, to the hyponychium. The nail bed contains blood vessels, nerves, and melanocytes that produce melanin.
How can I tell if my nail matrix is damaged?
If the matrix is destroyed it will not be able to create the nail. If there is minor damage it will be seen by a ridge or groove in the emerging nail. This can heal and the nail will grow without any noticeable damage. More serious damage can result in a permanent fault seen in the nail plate.

This is where new nail plate cells are created and as these new cells are created, older cells are pushed forward and the nail plate grows. The shape and size of the matrix determines the thickness and width of the nail. The longer the matrix, the thicker the nail, and vice versa. Damage to the matrix can cause a range of different nail imperfections, such as white spots or ridges, and weaken the nail plate as a whole.

What keeps the nail plate and protects it?
The hyponychium (informally known as the “quick”) is the epithelium located beneath the nail plate at the junction between the free edge and the skin of the fingertip. It forms a seal that protects the nail bed.
What happens when the nail matrix is damaged?
Finally, if the distal portion of the matrix is damaged, it affects the lowest part, or bottom of the nail plate. When this happens, it interferes with the attachment of the nail plate to the skin underneath (the nail bed) and can cause separation of the nail plate from the nail bed (onycholysis).
How do you get rid of Matrix nails?
If you want to avoid future infection by preventing the nail from growing back, your doctor can destroy the nail matrix. This is accomplished by applying a chemical to the cuticle area after the nail plate is removed. An ointment is applied to the wound, which is then covered with gauze and tape.
What are the 5 parts of the nail?
A fingernail consists of several parts including the nail plate (the visible part of the nail), the nail bed (the skin beneath the nail plate), the cuticle (the tissue that overlaps the plate and rims the base of the nail), the nail folds (the skin folds that frame and support the nail on three sides), the lunula (the.
Can a damaged nail matrix heal?
Many injuries to your nail bed can be fully repaired. For example, your nail should return to normal after a subungual hematoma is drained. However, some severe injuries can lead to a deformed nail. This is more likely when the base of your nail bed is injured.

In most cases, the nail will grow back from the area under the cuticle (the matrix). A fingernail takes about 4 to 6 months to grow back. A toenail takes about 12 months to grow back. If the nail bed or matrix was damaged, the nail may grow back with a rough or abnormal shape.
What is nail matrix infection?
The infection is caused by a fungal microbe that invades the nail bed. Fungal nail infection is also termed onychomycosis and tinea unguium.

What is the nail in a toe?
Anatomical terminology. A nail is a claw-like plate at the tip of the fingers and toes in most primates . Nails correspond to claws found in other animals. Fingernails and toenails are made of a tough protective protein called alpha-keratin, which is a polymer.
Why do my nails turn pink?
Protein is a building material for new nails; therefore, low dietary protein intake may cause anemia and the resultant reduced hemoglobin in the blood filling the capillaries of the nail bed reflects varying amounts of light incident on the nail matrix resulting in lighter shades of pink ultimately resulting in white nail beds when the hemoglobin is very low. When hemoglobin is close to 15 or 16 grams, most of the spectrum of light is absorbed and only the pink color is reflected back and the nails look pink.
How is the thickness of a nail determined?
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 matrix will continue to produce cells as long as it receives nutrition and remains in a healthy condition.
