| Arch | a fingerprint pattern in which the ridge pattern originates from one side of the print and leaves from the other side |
| Core | a center of a loop or whorl |
| Delta | A triangular ridge pattern with ridges that go in different directions above and below a triangle |
| fingerprint | an impression left on any surface that consists of patterns made by the ridges on a finger |
| latent fingerprint | a hidden fingerprint made visible through the use of powders or other techniques |
| loop | a fingerprint pattern in which the ridge pattern flows inward and returns in the direction fo the origin |
| minutiae | the combination of details in the shapes and positions of ridges in fingerprints that make each unique; also called ridge characteristics |
| patent fingerprint | a visible fingerprint that happens when fingers with blood, ink, or some other substance on them touch a surface and transfer the pattern of their fingerprint to that surface |
| plastic fingerprint | a three-dimensional fingerprint made in soft material such as clay, soap, or putty |
| ridge pattern | the recognizable pattern of the ridges found in the end joints of fingers that form lines on the surfaces of objects in a fingerprint. They fall into three categories: arches, loops, and whorls |
| ten card | a form used to record and preserve a person's fingerprints |
| whorl | a fingerprint pattern that resembles a bull's-eye |
| basal layer | a special layer within the epidermis where new skin cells are produced |
| epidermis | the basal layer is located here |
| fingerprint identification | recognizing the details in the differences between ridges, their reltive number, and their location on a specific fingerprint |
| Tape | used to lift and preserve a fingerprint |
| IAFIS | privides digital, automated fingerpint searches, latent searches, electronic storage of fingerprint photo files, and electronic exchange of fingerprints |
| cheiloscopy | the study of lip prints |
