Further Explanation:

Nails begin growing out the nail matrix this matrix creates this matrix forms new skin cells which forces all the cells all that sells out creating nails those injuries to mail to the nail bed orders orders or issues affecting the metrics often can lead to destruction of nail growth

The nail plate is immediately viewable with the naked eye, and covers the nail bed, which is the region where the nail sticks to the finger. Over this section is the lunula, the white half moon shapes at the base of the nail . The nail matrix  is the region directly before the lunula the germinal matrix below the lunula and closest to the knuckle where most of the nail  production occurs.  The periosteum, are structures surrounding nail plateswhile  the cuticle is a region of skin which protects the nail matrix where nails grow out of the finger. Every month nails typically grow up to 3 to 4 mm.

4. Part of the nail that covers the tender part of your finger: Nail plate

5. Part of the nail that extends over your finger: Free edge

6. Nails that need to be trimmed once a week: Fingernails

7. Nails that need to be trimmed every two weeks: Toenails

9. When the corner of a toenail grows into the flesh of the nail bed: Ingrown toenail

1. The nail matrix is the area where the nail is formed, located at the base of the nail beneath the cuticle. It contains the cells that produce the nail plate.

2. The lunula is the white, crescent-shaped area at the base of the nail matrix. It is the visible part of the nail matrix and appears as a whitish or pale semicircle.

3. The cuticle is the thin layer of skin that covers the base of the nail. It provides protection for the nail matrix and acts as a seal to prevent infection.

4. The nail plate is the hard, flat part of the nail that covers the tender part of your finger. It is composed of keratin and grows from the nail matrix.

5. The free edge is the part of the nail that extends over your finger beyond the finger tip. It is the portion that can be trimmed and is usually visible beyond the fingertip.

6. Fingernails typically grow at a faster rate than toenails and may need to be trimmed once a week to maintain an appropriate length.

7. Toenails usually grow at a slower rate than fingernails and may need to be trimmed every two weeks to prevent them from becoming too long.

8. Hangnails are small, torn pieces of skin at the side or base of the nail that can result from dry or dehydrated skin. They are often caused by not keeping the hands moisturized.

9. An ingrown toenail occurs when the corner of a toenail grows into the flesh of the nail bed, causing pain, swelling, and potential infection. It requires proper care and treatment to alleviate discomfort and prevent complications.
