Source:
A fingerprint pattern type in which one or more friction ridges enter upon one side, recurve, touch, or pass an imaginary line between delta and core and flow out, or tend to flow out, on the same side the friction ridges entered. Types include:
- left slant loops, in which the pattern flows to the left in the impression;
- right slant loops, in which the pattern flows to the right in the impression;
- radial loops, in which the pattern flows in the direction of the radius bone of the forearm (i.e., toward the thumb); and ulnar loops, in which the pattern flows in the direction of the ulna bone of the forearm (i.e., toward the little finger).
