A nail plate, also known as the nail lamina, is a hard, protective layer that covers the distal end of the finger or toe. It is composed of keratin, a protein that is also found in hair and skin. The nail plate is attached to the underlying nail bed by the nail matrix, which is located at the base of the nail. The nail plate is typically smooth and shiny, and it helps to protect the finger or toe from injury.
What is a Nail Plate?
The nail plate is the hard, protective covering on the end of your fingers and toes. It is made of a protein called keratin, which is also found in hair and skin. The nail plate protects the underlying tissue from injury and helps us to grip and manipulate objects.
Structure of the Nail Plate
The nail plate is made up of three layers:
- The dorsal nail matrix: This is the base of the nail plate, where new cells are produced.
- The ventral nail bed: This is the layer of tissue that supports the nail plate and provides it with nourishment.
- The nail plate itself: This is the hard, outermost layer of the nail.
Growth of the Nail Plate
The nail plate grows from the dorsal nail matrix. As new cells are produced, they push the old cells outward, causing the nail plate to grow. The nail plate grows about 0.1 millimeters per day, or about 3-4 millimeters per month.
Function of the Nail Plate
The nail plate serves a number of important functions, including:
- Protection: The nail plate protects the underlying tissue from injury.
- Grip: The nail plate helps us to grip and manipulate objects.
- Sensory feedback: The nail plate contains nerve endings that provide sensory feedback to the brain.
Common Nail Problems
A number of common nail problems can affect the nail plate, including:
- Onycholysis: This is a condition in which the nail plate separates from the nail bed.
- Paronychia: This is an infection of the nail fold.
- Nail fungus: This is a fungal infection of the nail plate.
- Psoriasis: This is a skin condition that can affect the nails, causing them to become thick and brittle.
Care for the Nail Plate
You can help to keep your nail plates healthy by:
- Keeping them clean: Wash your hands and feet regularly, and trim your nails regularly.
- Moisturizing them: Apply a moisturizer to your nails and cuticles every day.
- Protecting them from injury: Wear gloves when working with sharp objects or chemicals.
- Seeing a doctor if you have a nail problem: If you have a nail problem that does not go away, see a doctor for diagnosis and treatment.
