What common nail disorder features ridging and brittle texture?

• A. Onychomycosis
• B. Onychorrhexis
• C. Onychogryphosis
• D. Paronychia

Answer: (B)

Onychorrhexis is a nail disorder characterized by ridges and a brittle texture. This condition results from various factors, including environmental damage, underlying health issues, or nutritional deficiencies. The ridging occurs due to the irregular growth patterns of the nail plate, leading to structural weaknesses. As a result, the nails may easily chip or break, making them appear fragile and compromised.

In contrast, onychomycosis refers to fungal infections that often lead to discoloration and thickening of the nails rather than ridging. Onychogryphosis is marked by an abnormal curvature or thickening of the nail, typically not associated with ridging and brittleness. Paronychia is an infection of the skin around the nail, which may cause swelling and redness but does not specifically lead to ridged or brittle nails.
