Which condition is characterized by the presence of ridges on the nail plate?

• A. Onychomycosis
• B. Onychorrhexis
• C. Beau's lines
• D. Leukonychia

Answer: (C)

The presence of ridges on the nail plate is best identified by Beau's lines. These lines are deep grooves that run across the nail and can indicate a temporary interruption in nail growth, often due to underlying health issues, trauma, or serious illness. They reflect periods of systemic stress or change that have affected the nail matrix. While onychomycosis refers to a fungal infection of the nail, and onychorrhexis involves split or brittle nails with longitudinal ridges, these conditions do not produce the specific transverse grooves characteristic of Beau's lines. Leukonychia is associated with white spots or discoloration on the nail, which also does not pertain to ridges. The unique characteristic of Beau's lines, therefore, directly highlights the physical manifestation of ridges on the nail plate.
