What condition is indicated by splitting of the nail plate?

• A. Onychoschizia
• B. Nail pitting
• C. Onychomycosis
• D. Hangnail

Answer: (A)

The condition indicated by the splitting of the nail plate is onychoschizia. This term specifically refers to the thinness or brittleness of the nails, which leads to the nail plates splitting or peeling, particularly at the tips. This condition can be caused by various factors, including environmental conditions, excessive exposure to water, or nutritional deficiencies. The distinct characteristic of onychoschizia is the horizontal splitting of the nail, as opposed to other nail conditions, which may present differently.

Nail pitting, on the other hand, involves the formation of small depressions or pits on the surface of the nails, often associated with conditions like psoriasis and does not involve splitting. Onychomycosis refers to a fungal infection of the nail that can cause changes in color, thickness, and texture but is not characterized by splitting. A hangnail is a small tear of the skin around the nail, rather than a condition affecting the nail plate itself. Therefore, onychoschizia is the most accurate term for the splitting of the nail plate.
