New approach in expert opinion on peculiarities of palmar dermatoglyphics

Dermatoglyphics as a complex of provisions relating toskin designs includes a number of special notions defining the corresponding areas of research. These are: dactylography, palmography,iplantoglyphics, which study palm skin design and feet skin design respectively. As for palmar dermatoglyphics, no works dealing withthe prognostic estimation of human characteristics have been found. A sufficiently complete research of palmar dermatoglyphicsconcerns only the identification of a person by establishing the relationship. On the basis of the above, the purpose of this work iselaboration of methods of dermatoglyphic analysis of palmar skin design that can make it possible to estimate the results obtained in thecourse of research more completely; and this will inevitably simplify the application of dermatoglyphics in experts' daily work. For strictperception and uniformity, a new terminology of palmar dermatoglyphic characteristics was introduced into the scientific use. Thewhole characteristic of dermatoglyphic peculiarities was estimated with regard to thirteen triradii of palmar surface. The names of alltriradii (deltas) begin with Latin letter ''D'' (delta), then comes its ordinal number, which depends on the frequency of triradii display(excluding those of fingers). We have considerably increased the number of points between which the estimation of crest counting isdone. So, all lines along which crest counting is done are located with regard to basic and additional triradii. Five main groups ofquantitative indicators referring to the corresponding triradii (deltas), each covering several parts, have been determined. All these partsrepresent the absolute number of skin lines between points on palmar surface, which include the centers of triradii (deltas ) and strictlydefined points or places of segment ends directed from the center of a triradius and dividing delta into equal angels. When characterizingthe crest counting we took into account the number of palmar lines between triradii and between a triradius and a corresponding point onbending folds and palmar skin designs. To make the perception easier all characteristics of crest counting were divided into kinds,groups, types and ''floors''. As far as the characteristic of display of qualitative dermatoglyphic palm manifestations is concerned, it isfounded on the mode based on the presence on the palm of a so called ''main'' loop, the presence or absence of main and additionaltriradii. So, application of the proposed approach of palmar dermatoglyphics estimation is possible when studying the dermatoglyphicsof both the whole palm and its separate segments (upper, middle and lower ''floors''). The study of palm dermatoglyphics on the basis ofthe proposed approach makes it possible to generalize and work out the methods of dermatoglyphic analysis both under a separate studyof palmar surface and, in complex, under the study of skin design of fingers and feet.
