Study Notes
Fingerprint Patterns
- Loops are the most common fingerprint pattern
- Ulnar loops open towards the pinkie finger
- Radial loops, which open toward the thumb are less common
- Whorls are fingerprint patterns that appear as concentric rings
- Whorls can be spiral, oval, circular or any other round shape
- To identify fingerprint patterns, observe the entire pattern area rather than focusing on individual details
- Some fingerprints may blend two or more patterns, making them difficult to categorize
