Fingerprint ID (GMU)

QuestionAnswer
Corrugated skin on the Volare areas that enhances friction of the surface Friction ridge skin (FRS)
An area comprised of the combination of ridge flow, ridge characteristics, and ridge structure Friction ridge detail
A raised portion of skin found on the Palmar and plantar skin Friction ridge
Valleys or depressions btw friction ridges Furrows
Used to refer to any impression of or left by, friction ridge skin Fingerprint, friction ridge impression
-A transferred impression of friction ridge detail that is not readily visible to the naked eye. -A generic term used for a friction ridge impression that was unintentionally recorded. Composed primarily of water but has other constituents as well. latent print
-An intentional recording of the FRS of the distal phalanges. -A generic reference to exams performed on intentionally recorded friction ridge impressions. -A controlled record of fingers using ink, electronic imaging, or other medium. Record Print (Tenprint, Known Prints, Exemplar) (RP)-
An immature ridge. Usually, thinner and smaller than surrounding ridges. Incipient Ridge, Nascent Ridge, Rudimentary ridge-
A substance on the finger that makes latent prints possible. Fingerprint Goo
-A unique group of friction ridge detail that stands out enough for an examiner to easily memorize it. When the same group is located in an exemplar then recognition is triggered and a detailed comparison can begin. Target Group
-A distinctive group of ridge features (and their relationships) that can be recognized. Target Group 2
Palmar and plantar fetal tissue growth that affects friction ridge skin development and finger/toe patterns. Volar Pads
The acronym for the process of analyzing impression information, performing a visual comparison, arriving at a conclusion and having the conclusion verified. Analysis, Comparison, Evaluation, Verification (ACE-V)-
Where is the interdigital area? Palm area below the fingers
Where is the thenar area? Palm area next to the thumb
Where is the hypothenar area? Rest of the palm area; below interdigital area and next to thenar area
What are the 3 Galton Levels? First level- Overall pattern (loop, whorl, arch) Second level- Ridge path (i.e. bifurcation, ridge ending, dot) Third level- Ridge shape
Which Galton levels can an examiner used to identify a friction ridge impression? 2nd & 3rd
3 Premises of Fingerprint Identification -Permanent (Persistent) -Unique (Highly variable) -Can be classified
