Fingerprint Patterns & Minutiae

Front

What is a Bifurcation in fingerprint analysis?

Back

A bifurcation is a type of minutiae where a single ridge splits into two separate ridges, resembling a fork.

Front

What is a patent print?

Back

A patent print is a visible fingerprint impression left at a crime scene, often made by fingers coated in a substance like ink or blood.

Front

Identify the fingerprint pattern that resembles a loop.

Back

A loop is a fingerprint pattern characterized by ridges that enter from one side, loop around, and exit on the same side.

Front

What is the core in fingerprint analysis?

Back

The core is the central part of a fingerprint pattern, often found in whorls and loops, where the ridges converge.

Front

What is a ridge ending?

Back

A ridge ending is a type of minutiae where a ridge terminates abruptly.

Front

What is an island in fingerprint analysis?

Back

An island is a type of minutiae that appears as a single ridge that is not connected to any other ridges.

Front

What is a delta in fingerprint patterns?

Back

A delta is a triangular area found in fingerprint patterns, typically located near the core, where ridge lines diverge.

Front

What is the difference between a loop and an arch in fingerprints?

Back

A loop has ridges that enter and exit from the same side, while an arch has ridges that rise in the center and exit on opposite sides.

Front

What is a whorl in fingerprint patterns?

Back

A whorl is a fingerprint pattern characterized by circular or spiral ridges that form a complete circuit.

Front

What is a bridge in fingerprint analysis?

Back

A bridge is a type of minutiae where two ridges are connected by a small ridge.
