Friction ridges or papillary ridges Elevated strips of skin that begin as raised apertures around the pores and then are joined together into rows forming the ridges. ISABELA STATE UNIVERSITY Cauayan Campus A Review Material on Personal . In the 1920s, the FBI establishes its fingerprint identification division, which eventually leads to the addition of two more divisions to the original Henry system. Click here to review the details. In case of whorl pattern, the ridge counting is performed in the manner for right little finger, the ridge counting is done from left delta to core of the pattern and for the left little finger, the ridge counting is done from right delta to the core . If the male score (MS) is higher than the female score (FS), the decision is declared as male, otherwise it is declared as female. This extension is used to subdivide the primary classification groups where all the fingers have loop patterns. These frictions are provided during the birth to provide firm grasping and resistance to slipping. where RCF and FTSF are the respective scores of ridge count and fingertip size assigned for female fingerprints. The fingertip size of male and female fingerprints irrespective of the age group is analyzed and represented in Table3. \hfill \\ \end{aligned} $$, $$ {\rm FTS} {\text{ score }} = \, \frac{{{\text{Occurrence }}\% {\text{ of a particular FTS}}}}{{{\text{Maximum occurence }}\% }} \times 100. https://doi.org/10.1007/s40747-019-0099-y, DOI: https://doi.org/10.1007/s40747-019-0099-y.
