Study Notes

Minutiae Patterns

Ridge Ending: A specific point where a ridge terminates; crucial for fingerprint analysis.
Fork/Bifurcation: The point where a single ridge splits into two separate ridges; serves as a key feature for identification.
Island Ridge/Short Ridge: A small ridge that flows between two longer ridges; an important detail in fingerprint comparisons.
Dot: A small, isolated ridge that does not connect to other ridge patterns; significant for unique fingerprint characteristics.
Bridge Minutiae: A connection between two ridges that is not continuous but forms a bridge-like appearance; useful in forensic identification.
Spur/Hook: A ridge that abruptly changes direction or creates a small protruding point; noteworthy for enhancing the individuality of fingerprints.
Eye: A circular or oval shape formed by ridges; helps in differentiating between various fingerprint patterns.
Double Bifurcation: A feature where a ridge splits into two branches that then split again; adds complexity to fingerprint patterns.
Delta: A triangular area found in fingerprint patterns where ridges converge; essential for classifying fingerprint types.
Trifurcation: A point where one ridge divides into three individual ridges; rare and significant for fingerprint analysis.
Loop Pattern: A common fingerprint pattern characterized by ridges that enter from one side, recurve, and exit from the same side; classified into radial and ulnar loops.
Whorl Pattern: A fingerprint pattern that forms concentric circles or spirals; includes various subtypes, such as plain whorls and central pocket loops.
Arch Pattern: A fingerprint pattern where ridges enter from one side and exit the other without looping back; consists of plain arches and tented arches.
