Across
  1. 3. similar to the plain arch but has a more pronounced up-thrust or spiking ridge in the center, forming a tent-like shape.
  2. 4. a center of a loop
  3. 7. a three-dimensional fingerprint made in soft material such as clay, soap, or putty
  4. 11. a visible fingerprint produced when fingers coated with blood, ink, or some other substance touch a surface and transfer their print to that surface
  5. 13. the recognizable pattern of the ridges found in the end pads of fingers that form lines on the surfaces of objects in a fingerprint. They fall into three categories: arches, loops, and whorls. They are also visible on the soles of feet and bottoms of toes
  6. 14. a triangular ridge pattern created when ridge patterns diverge
  7. 15. uses measurements and statistical analyses of someone’s physical characteristics to aid in their identification
  8. 16. the combination of details in the shapes and positions of ridges in fingerprints that makes each unique; also called ridge characteristics
  9. 17. the ridges flow in a loop pattern that opens toward the little finger (ulnar side) of the hand.
  10. 20. the spaces or grooves between the ridges. They appear as the lower, depressed lines on a fingerprint, contrasting with the elevated ridges.
  11. 21. consists of two distinct and separate loop formations within the same fingerprint, resembling an "S" shape.
  12. 22. a form used to record and preserve a person’s fingerprints
Down
  1. 1. pattern that features ridges that form a loop opening toward the thumb (radial side) of the hand.
  2. 2. an impression left on any surface that consists of patterns made by the ridges on a finger
  3. 5. Patterns the tiny sweat pores located along the ridges of a fingerprint.
  4. 6. Identification System (IAFIS) FBI-developed national database of more than 76 million criminal fingerprints and criminal histories
  5. 7. a fingerprint pattern in which the ridge pattern originates from one side of the print and continues to the other side
  6. 8. a loop with a whorl inside it, where the central pocket loop has a recurving ridge, or an obstruction at a right angle to the loop.
  7. 9. a complex pattern that doesn't conform to any of the standard types. It may combine multiple patterns or have unusual ridge formations.
  8. 10. a concealed fingerprint that is made visible through the use of powders or forensic techniques
  9. 12. a fingerprint pattern that resembles a bull’s-eye
  10. 18. the number of ridges between the center of a delta and the core of a loop
  11. 19. the raised lines on the skin of the fingertips. They form the patterns that are unique to each individual and are used for identification. Ridges help improve grip and sensitivity to touch.
