archA fingerprint pattern in whichthe ridge pattern originates
from one side of the print andleaves from the other side
5%Arch fingerprints are
found in this percent ofthe population
core The center of a loop orwhorl pattern
dactylographydactyloscopy
Give the two possiblenames for the branch of
science which studiesfingerprints
dermal or friction ridgesRaised portions of the
skin, arranged inconnected units, which
form fingerprints
delta
A triangular ridge pattern withridges that go in differentdirections above and below atriangle; found in all loop andwhorl patterns
fingerprintAn impression left on any
surface that consists ofpatterns made by ridges
on the tip of a finger
loopA fingerprint pattern in
which the ridge enters fromone side, curves, then exits
on the same side
65%Loop fingerprints are
found in this percent ofthe population
latentA hidden fingerprint
made visible through theuse of powders or other
techniques
minutiae
The combination of details inthe shapes and positions ofridges in fingerprints that makeeach unique; also called ridgecharacteristics
patentA fingerprint that happens whenfingers with blood, ink, chalk,grease or dirt on them touch asurface and transfer the pattern oftheir fingerprint to that surface
plasticA three-dimensional
fingerprint made in softmaterial such as clay,
soap, paint, putty, or wax
whorl A fingerprint pattern thatresembles a bull's-eye
30%Whorl fingerprints are
found in this percent ofthe population
ridge These appear dark on afingerprint image
valley These appear white on afingerprint image
10thFingerprints typically
form during this week ofpregnancy
epidermis The outermost layer ofskin
dermis The innermost layer ofskin
basal layerThese cells grow faster than
the layers above and below soit collapses and folds to form
the shapes of a fingerprint
apocrineType of sweat glandsassociated with hair
follicles
eccrineType of sweat glandsassociated with the
hands and feet
loop The most commonfingerprint pattern
arch The least commonfingerprint pattern
tented This type of arch patternhas a spike in the middle
radialOn the right hand, this
loop pattern openstowards the left
ulnarOn the left hand, thisloop pattern opens
towards the left
double loopThis whorl pattern ismade up of any two
loops combined into oneprint
accidentalWhorl Fingerprint type consistingof a combination of two differenttypes of patterns or whichconforms to none of the normalfingerprint type definitions
12To be absolutely certaintwo prints match, theymust have this many
common minutiae
8The maximum number of
minutiae found to beshared between twodifferent individuals
bifurcation Minutiae pattern thatlooks like a "Y"
tape Method used to liftfingerprints after dusting
cyanoacrylate Super glue fingerprintingmethod
ninhydrinThis fingerprint test resultsin a purple-blue print whenamino acids found in sweat
react with this chemical
silver nitrateChloride from salt in
sweat on a printcombines with this to
form dark colored prints
iodineFuming this chemicalcauses fingerprints to
appear brown thenquickly fade
individual Fingerprints are this typeof evidence
Galton-Henry Method of fingerprintingstill used today
AFISFBI's electronic storageand search program for
fingerprints
50 millionThe number of fingerprints
stored in the IntegratedAutomated FingerprintIdentification System
2 hoursThe time it takes AFIS to
produce a list of potentialmatches from a
