1. Loop Type Based on Opening Towards Forearm Bones (Radial and Ulnar Loops) A loop fingerprint is broadly subcategorized into radial and ulnar loops. Their names are based on the …

Radial and ulnar loops. The terms "radial" and "ulnar" are derived from the radius and ulna bones of the forearm. Loops which flow in the direction of the ulna bone (toward the little finger) are …

Loops - prints that recurve back on themselves to form a loop shape. Divided into radial loops (pointing toward the radius bone, or thumb) and ulnar loops (pointing toward the ulna bone, or …

Nov 1, 2023 · Just like the radial loop, ulnar loops exhibit variations within their pattern, making fingerprint analysis a nuanced field. In an ulnar loop, the ridges flow toward the pinky finger, …

Ulnar Loop. These are named after the ulna, a bone located in the forearm. This bone is located on the same side of the hand as the little finger, and this pattern flows from the thumb to the …

An ulnar loop is defined as a loop with the ridges entering and exiting on the side that is closest to the pinky finger. It is called ulnar loop because the ridges dump out closest the ulna bone in …

Mar 3, 2025 · Ulnar loops, flowing toward the little finger, dominate the right hand. Like their radial cousins, they appear in two forms: Plain ulnar loops create gentle, continuous flows; Tented …

Oct 21, 2014 · Our results show that there are systematic size and shape differences between radial and ulnar loops on index fingers, primarily concentrated in the course of the distal type line.

If a loop opens toward the little finger, it is called an ULNAR LOOP; if it opens toward the thumb, it is a RADIAL LOOP. The patterned area of any loop is surrounded by two TYPE LINES. All …
