FSC100H5 Lecture Notes - Lecture 12: Ulnar Nerve, Ulna
Document Summary
One was incarcerated, the other was brought in for processing, they realized that they had a duplicate (brother) b/c of very similar bertillion measurements. Loop: ulnar: ulna bone, 92%, if opening of pattern is towards the right side, radial: radius bone, opening of pattern is towards the left side. Look at where the core is (lower or higher) Why is it important: can narrow search down, time, minimize resources needed, cost saving. Friction ridge patterns vary within limits which allows for classification. 1st level: pattern, core and pores delta (can use for elimination purposes, but not identifications: overall ridge flow. 2nd level: minutiae and incipient ridges (identifications and exclusions can occur: ridge path, characteristics . Spatial relationship: continuous ridges, galton details. 3rd level: ridge levels (identification and exclusion can be supported at this level: size and shape of pores and ridges.
