define dermatoglyphics
From Wikipedia, the free encyclopedia. Dermatoglyphics (from ancient Greek derma=skin, glyph=carving) is the scientific study of fingerprints, lines, mounts, and shapes of hands. Dermatoglyphics refers to the formation of naturally occurring ridges on certain body parts, namely palms, fingers, soles and toes. These are areas where hair usually does not grow and these ridges allow for increased leverage when picking up objects or walking barefoot.
The term rash has no precise meaning but often is used to refer to a wide variety of red skin eruptions. A rash is any inflammatory condition of the skin. Dermatologists have developed various terms to describe skin rashes. The first requirement is to identify a primary, most frequent feature.
