Fingerprints

T

ake a close look at the tips of your fingers. Can you

see swirling lines? These lines are made by ridges and

furrows in your skin. The ridges help you grip objects.

Without them, things might slip from your hands. Everyone

has these ridges. They are your

fingerprints

. Your

fingerprints grow larger as your body grows, but they do

not change in any other way. Your fingerprints are unique.

No one else has exactly the same design. Not even identical

twins have fingerprints that are exactly the same. The

Chinese started using fingerprints as marks of identification

around 200 BCE.

The shape of a fingerprint is called its pattern. Fingerprints

can be separated into three general patterns. They are

arches

,

loops

, and

whorls

. Ridges in an arch start on one side of a

finger, rise and fall in the center of the finger, then end on

the other side of the finger. Ridges in a loop also start on one

side of the finger. But they rise and curve back to end on the

same side they started. A whorl is a set of circles inside each

other, formed by ridges.
