10/23-24 Fingerprint Practice

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, and is a key reference point for classification.

Front

Define a whorl fingerprint pattern.

Back

A whorl fingerprint pattern is characterized by circular or spiral ridges that make a complete circuit, with at least two deltas.

Front

What is a double loop whorl?

Back

A double loop whorl is a fingerprint pattern that consists of two separate loop formations, creating a complex pattern.

Front

What is a loop in fingerprint patterns?

Back

A loop is a fingerprint pattern that flows in one direction and returns in the opposite direction, with one delta.

Front

What is an arch in fingerprint patterns?

Back

An arch is a fingerprint pattern that has ridges that enter from one side and exit on the other side, with no deltas.

Front

Identify the characteristics of a central pocket loop.

Back

A central pocket loop is a fingerprint pattern that has one core and one delta, with ridges that loop back on themselves.

Front

What is an accidental whorl?

Back

An accidental whorl is a fingerprint pattern that does not fit into the standard categories of loops or whorls and has a combination of features.

Front

How do you identify a delta in a fingerprint?

Back

A delta is identified as a triangular ridge pattern that is found in loop and whorl fingerprints, indicating a change in ridge flow.

Front

What is the significance of fingerprint patterns in forensic science?

Back

Fingerprint patterns are unique to individuals and are used for identification in forensic science, criminal investigations, and security.

Front

Explain the difference between a plain whorl and a central pocket loop.

Back

A plain whorl has two deltas and a complete circuit, while a central pocket loop has one delta and a loop that returns to the core.
