A mark left by a finger when something is touched.
A unique pattern of lines and swirls in the skin found at the end of each finger. When the fingertips are used to touch certain surfaces, they leave an impression of the characteristic pattern of lines. Because they are unique, these impressions can be used to identify the person to whom they belong. Individual fingerprints are recorded by making an ink impression for the purpose of identification.
The distinctive pattern of minute ridges in the outer horny layer of the skin. Every individual has his or her own unique pattern, though there are six basic fingerprint formations: double loop, tented loop, radial loop, arch, whorl, and ulnar loop. Fingerprint patterns can show the presence of inherited disorders.
A smudge made when oils from the distal portions of the finger come into contact with an object. Fingerprints are used in forensics for personal identification.
A mark left on a surface from the intricate curved ridge pattern on a fingertip’s skin is known as a fingerprint. These ridge patterns are classified into four types: loops, arches, whorls, and compounds, which are a mixture of the other three types. Remarkably, no two individuals, including identical twins, share identical fingerprints.
