___ loops enters and exits toward the thumb.
-
Radial
-
Arch
-
Ulnar
Correct Answer
A. RadialExplanation
The statement suggests that the loops enter and exit towards the thumb. Among the given options, the only artery that follows this pattern is the radial artery. The radial artery runs along the thumb side of the forearm and supplies blood to the forearm and hand. Therefore, the correct answer is radial.Rate this question:

There are ____ number of patterns and ___ number of sub-patterns.
-
3 patterns and 8 sub-patterns
-
4 patterns and 3 sub-patterns
-
8 patterns and 3 sub-patterns
Correct Answer
A. 3 patterns and 8 sub-patternsExplanation
The question states that there are a certain number of patterns and sub-patterns. The correct answer states that there are 3 patterns and 8 sub-patterns. This means that there are three main patterns, and within each of these patterns, there are 8 sub-patterns.Rate this question:

___ loops enters and exits toward the little finger.
-
Radial
-
Arch
-
Ulnar
Correct Answer
A. UlnarExplanation
The correct answer is "Ulnar" because the ulnar loop is a type of fingerprint pattern that enters and exits toward the little finger. This pattern is characterized by a loop that starts on one side of the finger and curves back towards the same side, forming a loop that is tilted towards the little finger.Rate this question:
-
- 6.
A ___ is the spreading apart of two lines which have been running parallel or nearly parallel.
-
Divergences
-
Bifurcation
-
Pattern Area
Correct Answer
A. DivergencesExplanation
Divergences refer to the spreading apart of two lines that were previously running parallel or nearly parallel. This can occur in various contexts, such as in economics or in the study of fluid dynamics. When there is a divergence, the lines move away from each other, indicating a separation or a divergence in their paths or trajectories.Rate this question:
-
- 7.
The ____ is that point on a ridge at or in front of the nearest the center of the divergence of the type lines.
-
Angles
-
Focal Points
-
Delta
-
None of the above
Correct Answer
A. DeltaExplanation
The term "delta" refers to the point on a ridge where the type lines diverge. This point is located at or in front of the nearest center of the divergence. The other options, angles and focal points, do not accurately describe this concept. Therefore, the correct answer is delta.Rate this question:
-
- 8.
A ___ the ridges enter on one side of the impression and flow or tend to flow out the other with a rise or wave in the center.
-
Loop
-
Plain Arch
-
Tented Arch
Correct Answer
A. Plain ArchExplanation
A plain arch is a type of fingerprint pattern where the ridges enter on one side of the impression and flow or tend to flow out the other side with a rise or wave in the center. This pattern does not form a loop or tented arch, which makes the plain arch the correct answer.Rate this question:
-
- 9.
_____ may be defined as two innermost ridges which start parallel, diverge, and surround or tend to surround the pattern area.
-
Pattern Lines
-
Type Lines
-
Long Lines
Correct Answer
A. Type LinesExplanation
Type lines may be defined as two innermost ridges which start parallel, diverge, and surround or tend to surround the pattern area.Rate this question:
-
- 10.
Angles can be used as type lines.
-
True
-
False
Correct Answer
A. FalseExplanation
Angles cannot be used as type lines. Type lines are used in architectural or engineering drawings to indicate the type of line being used, such as a solid line for visible edges or a dashed line for hidden edges. Angles, on the other hand, are measurements of the space between two intersecting lines. They are not used to indicate the type of line being used in a drawing. Therefore, the statement is false.Rate this question:
-
- 11.
In regards to type lines when there is a definite break the ridge immediately _____ of it is considered its continuation.
-
Inside
-
Outside
-
Beside
Correct Answer
A. OutsideExplanation
When there is a definite break in the ridge, the ridge immediately outside of it is considered its continuation. This means that the ridge pattern continues on the outside of the break, rather than on the inside or beside it.Rate this question:
-
- 12.
Within the pattern areas of loops and whorls are enclosed the _____ which are used to classify them.
-
Focal Points
-
Angles
-
Type Lines
Correct Answer
A. Focal PointsExplanation
Within the pattern areas of loops and whorls, there are certain distinctive points called focal points. These focal points are used to classify the loops and whorls. They help in identifying and categorizing the different patterns in fingerprint analysis. The presence and positioning of these focal points play a crucial role in determining the type and classification of the fingerprint pattern.Rate this question:

A __ may be defined as that part of a recurving ridge between the shoulders of a loop.
-
Delta
-
Appendages
-
Sufficient recurve
-
None of the above
Correct Answer
A. Sufficient recurveExplanation
A "sufficient recurve" may be defined as that part of a recurving ridge between the shoulders of a loop. This means that when looking at a loop pattern, the sufficient recurve refers to the area between the two points where the ridge curves back towards the center of the loop. It is an important characteristic used in analyzing and classifying fingerprint patterns.Rate this question:
-
- 14.
Of all the fingerprints the most common print is loop. Of these loops 95% of them are ___.
-
Radial
-
Arch
-
Ulnar
Correct Answer
A. UlnarExplanation
The correct answer is "Ulnar." The explanation for this is that the question states that the most common type of fingerprint is a loop. It further specifies that out of all the loop fingerprints, 95% of them are ulnar loops. Therefore, ulnar is the correct answer as it represents the majority of loop fingerprints.Rate this question:
-
- 15.
____ are never formed by a single ridge but by the abutting of one ridge against another.
-
Bifurcations
-
Angles
-
Divergences
Correct Answer
A. AnglesExplanation
Angles are never formed by a single ridge but by the abutting of one ridge against another. This means that angles are created when two ridges meet or intersect with each other. Bifurcations, on the other hand, refer to the splitting or dividing of a ridge into two separate branches. Divergences are the spreading apart or separating of ridges. Therefore, only angles fit the given description.Rate this question:
-
- 16.
In ___ most ridges enter upon one side of the impression and flow or tend to flow out upon the other side.
-
Loop
-
Plain Arch
-
Tented Arch
Correct Answer
A. Tented ArchExplanation
In a tented arch fingerprint pattern, most ridges enter on one side of the impression and flow or tend to flow out on the other side. This means that the ridges form an upward peak in the center of the pattern, resembling a tent. This is different from a loop pattern where the ridges enter on one side and flow out on the same side, and a plain arch pattern where the ridges enter on one side and flow out on the opposite side without forming a peak.Rate this question:

Select all the essentials of a loop.
-
A core
-
A sufficient recurve
-
A delta
-
A ridge count
-
Appendages
Correct Answer(s)
A. A sufficient recurve
A. A delta
A. A ridge countExplanation
The essentials of a loop are a sufficient recurve, a delta, and a ridge count. A loop is a type of fingerprint pattern, and these characteristics are used to classify and identify fingerprints. A sufficient recurve refers to the curved ridge that starts inside the pattern and flows back towards it. A delta is a triangular ridge pattern found at the core of the loop. A ridge count is the number of ridges that cross a specific line in the pattern. These features are crucial in analyzing and comparing fingerprints for forensic purposes.Rate this question:
