Q.E 25

• Recurving or Looping Ridge - a kind of ridge formation that curves back in the direction from which it started.
• Sufficient Recurve - a recurving ridge complete in its shoulder and is free from any appendage
• Appendage - a short ridge found at the top or summit of a recurving ridge
• Rod or Bar - a short or long ridge found inside the innermost recurving ridge of a loop pattern.
• Obstruction Ridge - short ridge found inside the innermost recurving ridge that spoiled the inner flow towards the

  center of the pattern
• Fragmentary Ridge - a ridge of extremely short length having frequent breaks.
• Crossover or Bridge - a short ridge that runs between two parallel ridges.
• Ridge Dots - An isolated ridge unit whose length approximates its width in size.
• Bridges - A connecting friction ridge between parallel running ridges, generally right angles
• FOCAL POINTS - are enclosed within the pattern area.
• PATTERN AREA - is that part of a loop or a whorl in which appear the core, deltas, and ridges used in the classification of

  a loop.
• TYPELINES - The two innermost ridges which start or go parallel, diverge, and Surround or tend to surround the pattern

  area
• CORE - The inner terminus or the approximate center of a fingerprint pattern
• DELTA - The outer terminus or that point in a ridge at or in front of or nearest the center of the divergence of the

  typelines
• Plain Arch - a pattern in which the ridges flow from one side to the other without recurving
• Tented Arch - a pattern where one or more ridges at the center form an up trust
• Radial Loop - a loop in which the downward slope or the slanting ridges runs towards the direction of the thumb.
• Radial Bone - the inner bone of the forearm that runs to the wrist on the side where the thumb is located.
• Ulnar Loop - a loop in which the downward slope or the slanting ridges runs towards the direction of the little finger.
• Ulna Bone - the bone running to the wrist located or situated on the little finger.
