Arches-
Arches can be classified as a plain arch or as a tented arch.
A plain arch is a pattern where the ridge enters one side and flows out
of the opposite side. The ridges
rise or make a wave in the very center of the pattern.
A plain arch does not have any recurves, angles, upthrust, or looping
ridges. If any of these are
present in an arch pattern, then it is a tented arch pattern.
Tented arches may have at least two (2) of the same characteristics of a
loop. A tented arch may have a
ridge count, recurve, or even a delta present in the pattern.
Most tented arches have a looping ridge existing in the pattern, but this
does not hold true for all tented arches.
An easy way to remember a tented arch, is that it looks similar to a tent
like formation. The Henry Classification code for tented arches in fingers 2 and
7 is a capital T. In all fingers
other than 2 and 7, place a small t in the fingerprint block. If the print or
impression is classified as a plain arch, place a capital A in the box for
fingers 2 and 7, all other fingers that are not 2 or 7 will have a lower case a
to indicate a plain arch.
