What is the function of nail plate?
Nail plate: The nail plate is the actual fingernail, and it’s made of translucent keratin. The pinkish appearance of the nail comes from the blood vessels that are underneath it. The underside of the nail plate has grooves that run along the length of the nail and help anchor it to the nail bed.
Where is the nail plate?
The nail plate emerges from the proximal nail fold and is bordered on either side by the lateral nail folds (paronychium). The nail plate is composed of hard, keratinized, squamous cells that are loosely adherent to germinal matrix but strongly attached to the sterile matrix.
What is the anatomy of a fingernail?
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 …
What causes nail plate?
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.
How does the nail plate grow?
When cells at the root of the nail grow, the new nail cells push out the old nail cells. These old cells flatten and harden, thanks to keratin, a protein made by these cells. Your fingernails grow slowly — in fact, they grow about one tenth of an inch (2.5 millimeters) each month.

What are nail beds?
The nail bed is the pinkish-colored soft tissue underneath your nail plate (the hard part of your nail). Some people have shorter nail beds while others have longer ones. Some people are unhappy with their shorter nail beds because they feel it makes their nails look too short.
What are the 5 stages of nail growth?
There are five stages of nail growth, they are:
- Cells divide in the Matrix.
- New cells are pushed forward by constant cell reproduction.
- Cells undergo hardening, this is also known as Keratinisation.
- The growing nail is guided along the Nail Grooves and Side Walls.
- The Free Edge is formed away from the finger.
What are the 7 structures of nail?
The attached figure depicts the gross structures described below.
- Nail Folds. The nail folds are soft tissue structures that protect the lateral and proximal edges of the nail plate.
- Mantle.
- Cuticle.
- Nail Matrix.
- Nail Plate.
- Nail Bed.
- Hyponychium.
- Onychodermal Band.
What do nail plates need?
Nail plates need oxygen, vitamins, and minerals. 5. Toenails are thicker and harder than fingernails because the toenail Matrix is larger than the fingernail matrix.
What is nail plate separation?
Onycholysis is a common nail disorder in which the nail plate has separated from the nailbed typically resulting in a well-defined area of white opaque nail. It may be idiopathic or secondary to trauma, skin disease, nail infections, tumours, or systemic events.
What is the toe nail bed called?
The nail bed is the formation of cells that lies just under the nail plate. The nail plate is the main part of your toenail. The nail bed is also called the quick.
