Which type of loops flow in the direction of the radius bone?

Radial loops are characterized by their specific flow direction, which follows the same trajectory as the radius bone in the forearm. The radius is located on the thumb side of the arm, and radial loops open towards this side. In contrast, ulnar loops flow towards the little finger side, making them distinctly different from radial loops. Circular loops and concentric loops do not pertain to the anatomical orientation of the forearm and do not have a designation related to specific bones. Therefore, the identification of radial loops as the type that aligns with the direction of the radius bone is accurate and highlights the anatomical relationship that defines this type of fingerprint pattern.
