The nail root is located below the skin, underneath the nail, extending several millimeters into the finger.
Understanding the Nail Root Location
The nail root is a crucial part of your nail structure. It's where new nail cells are generated, which then push older cells forward to form the visible nail plate. Here's a breakdown of its location and features:
- Hidden from View: Most of the nail root is not visible as it is tucked away under the skin.
- Proximal Nail Fold: The skin that covers the nail root is known as the proximal nail fold.
- Below the Nail Plate: The nail root is situated underneath the nail plate, at the base of the nail.
- Extends into the Finger: It extends a few millimeters into the finger, where it produces the bulk of the nail's volume and the nail bed.
The Lunula: A Visible Part of the Nail Root
A small, visible portion of the nail root appears as a white crescent shape called the lunula.
- Location of the Lunula: The lunula can usually be seen at the base of the nail, near the cuticle.
- Not Always Visible: The lunula may not be visible on all nails or in all individuals.
Key Takeaways
| Feature | Description |
|---|---|
| Primary Location | Beneath the skin, under the nail plate |
| Function | Generates new nail cells, forming the majority of the nail and nail bed. |
| Visible Part | The lunula, which is a white crescent at the base of the nail. |
| Coverage | Mostly covered by the proximal nail fold. |
Example: The nail root is similar to the roots of a plant, producing growth that extends to form a nail.
