Ohio State Board Nail Technician Practice Exam

A severe injury to which parts will cause pterygium?

1. Eponychium or hyponychium

2. Matrix or nail bed

3. Cuticle or nail plate

4. Lunula or nail fold

The correct answer is: Eponychium or hyponychium

A pterygium is a growth of pink, fleshy tissue with blood vessels on the cornea of the eye. It is typically caused by chronic exposure to UV light, dry eye, allergies, and other factors. None of the other options listed are related to the eye and therefore cannot cause a pterygium. A The eponychium and hyponychium are both parts of the skin surrounding the nail, but they are located on the fingers and toes, not on the eye. B: The matrix and nail bed are part of the nail structure, not the eye. Additionally, the matrix is located under the nail fold which is listed in option D. C: The cuticle and nail plate are also part of the nail, not the eye. D: The lunula and nail fold are both part of the nail structure, not the eye. The correct answer
