whorl

This term evokes a sense of organic, mathematical precision. It is most frequently used in biological or forensic contexts to describe a specific type of curvature that curves inward toward a center point, creating a concentric or coiled appearance. It suggests a natural growth pattern rather than a random scribble. In a descriptive sense, it carries a neutral to clinical tone. While a swirl might feel chaotic or liquid, a whorl feels structured and permanent, like the ridges on a fingertip or the growth rings of a shell.
