A cosmetologist is explaining the structure of the nail plate to a client. Which component of the nail is directly responsible for producing the nail plate?
- AEponychium
- BNail Bed
- CNail Matrix
- DPerionychium
Show answer & explanationAnswer & explanation
Correct answer: C. Nail Matrix
The nail matrix is the specialized tissue located at the base of the nail plate, beneath the eponychium, where new nail cells are produced. It is solely responsible for the growth and formation of the nail plate.
Why the other options are wrong
- A. The eponychium (cuticle) is the living skin at the base of the nail plate, sealing the matrix area, but does not produce the nail plate.
- B. The nail bed is the skin underneath the nail plate, providing support and nourishment, but does not produce the nail plate itself.
- D. The perionychium is the skin surrounding the entire nail border, not the nail-producing part.
Nail Matrix
The active tissue at the base of the nail plate, hidden under the eponychium, responsible for producing new nail cells and thus the growth of the nail plate.
- Located at the base of the nail plate
- Responsible for nail growth
- Contains nerves, lymph, and blood vessels
- Damage can affect nail growth
