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 forearm bones i.e. Radius for radial loops and Ulnar for Ulnar loops.

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 pinky), loops account for approximately 60 percent of pattern types.

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 called ulnar loops and those which flow in the direction of the radius bone are called radial loops.

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 little finger. Radial Loop. These loops get their name from the radius bone, which connects the forearm to the hand on the same side as the thumb.

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, creating a looping pattern that opens in the direction of the little finger.

Jul 2, 2023 · 2. Loops. Around 60-65% of the recorded fingerprints are loop which makes it the most common fingerprint pattern in the population. A loop is formed when one or more ridges enter from a side (either left or right), continuing up to the center of the pattern, recurving around the core forming a loop, and then flowing back and terminating/exiting ...

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.

Jul 7, 2022 · Ulnar Loop is one of the most common fingerprint types and a subtype of Loop fingerprints. The Ulnar loop is characterized by its loop ridges coming from the left, swirling in a half-circle from the thumb to the pinky or the little finger on your hand.

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 the forearm.

Ulnar Loop. The ulnar loop is a loop-shaped pattern that resembles a waterfall which is flowing towards the little finger. Typically this pattern includes delta points.
