What are loops that flow in the direction of the radius bone called?

Radial loops are a specific type of fingerprint pattern characterized by the ridges that flow in the direction of the radius bone, which is located on the thumb side of the arm. This pattern is significant in the classification of fingerprints and is distinguished by how the ridges originate from the side of the thumb and flow towards the little finger. Identifying the orientation of the loop is essential for forensic analysis and can assist in the determination of individual fingerprint characteristics.

The definition and identification of radial loops are critical in the context of fingerprint examination, as they represent one of the primary types of patterns used to categorize and analyze fingerprints. Other fingerprint patterns like whorls and arches have distinct characteristics that differentiate them from loops, and understanding these differences aids fingerprint analysts in making accurate identifications.
