What are corrugations in the nail?

Appear blush in color
Horizontal wavy ridges
Ringworm of the hand
Thin, soft nails

The correct answer is: Horizontal wavy ridges

Corrugations in the nail refer to horizontal wavy ridges that can appear on the nail surface. This condition can be caused by various factors, such as trauma, nutritional deficiencies, or certain medical conditions. The presence of these ridges indicates a disruption in the normal nail growth process and can often be a visual indicator of underlying issues. The other options do not accurately describe corrugations. For instance, a blush color typically refers to discoloration, which is not characteristic of corrugations. Ringworm of the hand pertains to a fungal infection and is unrelated to nail texture or ridging. Lastly, thin, soft nails relate to nail texture and strength and do not describe the specific horizontal wavy pattern that defines corrugations.
