Course Description
The purpose of this course is to provide beneficial skills and knowledge applicable to the performance of friction ridge examinations of the palmar surfaces of human beings. Principal topics covered by the course include a brief history of friction ridge examination, the structure and morphology of friction ridge skin and the human hand, the dermatoglyphics and the topography of palmar friction ridge skin (including palmar regions, pattern areas, and creases), how to conduct side-by-side comparisons, and helpful tips for easier recognition of palmar friction ridge skin for efficient searching and comparisons.
