Fingerprint Patterns & Minutiae

Front

What is a fingerprint pattern?

Back

A fingerprint pattern is the unique arrangement of ridges and valleys on the surface of a fingertip, which can be classified into different types such as loops, whorls, and arches.

Front

What are the three main types of fingerprint patterns?

Back

The three main types of fingerprint patterns are loops, whorls, and arches.

Front

Define 'accidental whorl'.

Back

An accidental whorl is a fingerprint pattern that does not fit into the standard categories of loops or whorls and contains two or more different types of patterns.

Front

What is a 'tented arch'?

Back

A tented arch is a fingerprint pattern characterized by a central core that rises sharply, resembling a tent.

Front

What is a 'ridge ending'?

Back

A ridge ending is a point where a ridge in a fingerprint terminates or ends.

Front

Define 'bifurcation' in fingerprint analysis.

Back

Bifurcation is a point in a fingerprint where a single ridge splits into two separate ridges.

Front

What is a 'hook' in fingerprint minutiae?

Back

A hook is a type of minutiae where a ridge ends and then curves back on itself, resembling a hook.

Front

Explain the term 'short ridge'.

Back

A short ridge is a small segment of a ridge that is shorter than the average ridge length in a fingerprint.

Front

What is a 'bridge' in fingerprint patterns?

Back

A bridge is a connection between two ridges in a fingerprint, forming a small bridge-like structure.

Front

Define 'spur' in the context of fingerprints.

Back

A spur is a type of minutiae where a ridge bifurcates and one of the branches is shorter than the other, resembling a spur.
