A client says her cuticle is overgrown and sticking to the nail plate. What is the difference between the eponychium and the cuticle that a technician should know before servicing?
- AThe eponychium is living skin at the base of the nail, while the cuticle is the dead tissue that adheres to the nail plate
- BThe eponychium and cuticle are the same structure with different regional names
- CThe eponychium is dead tissue that can be safely trimmed, while the cuticle is living skin that must not be cut
- DThe eponychium is found only on toenails, while the cuticle is found only on fingernails
Show answer & explanationAnswer & explanation
Correct answer: A. The eponychium is living skin at the base of the nail, while the cuticle is the dead tissue that adheres to the nail plate
The eponychium is the living skin that overlaps the base of the nail plate, protecting the matrix, and should never be cut. The cuticle is the dead, colorless tissue that clings to the nail plate surface and can be gently pushed back and trimmed if overgrown.
Why the other options are wrong
- B. They are distinct structures with different compositions and functions.
- C. This reverses the correct definitions of the two structures.
- D. Both structures exist on fingers and toes, not restricted to one or the other.
Eponychium vs. Cuticle
The eponychium is living skin at the base of the nail protecting the matrix; the cuticle is dead, colorless tissue adhering to the nail plate that can be trimmed.
- Never cut the eponychium — risk of infection
- Cuticle can be gently pushed and trimmed if overgrown
- Both help seal out bacteria at the nail base
Memory trick: E for Eponychium, E for 'never Excise' — it's alive!
