DERMATOGLYPHIC IN BULGARIAN MEN - FINGER AND PALM RIDGE COUNT

ABSTRACT. The aim of the present study is to investigate the finger and palm ridge counts on both hands in a representative group of healthy Bulgarian men. Object of the study are the dermatoglyphic prints from both hands of 1161 healthy men from 116 settlements in the country. The analysis includes: ridge counts on each finger, summary finger ridge count for both hands separately, total finger ridge count; ridge count on each interdigital area, summary palm ridge count for both hands separately, total palm ridge count. The descendent formula of finger ridge count is identical for both hands – I>IV>V>III>II. Considerably higher is the mean summary finger ridge count in right. The distribution of individuals according to summary ridge count in right and left, as well as the total finger ridge count is asymmetrical, moved in left. The palm ridge count is biggest between digital triradii a-b, followed by c-d and b-c. The summary palm ridge count a-d is higher on right hand. The distribution of the individuals after summary palm ridge count a-d in right and left, as well as the total palm ridge count is almost symmetrical, slightly moved in left.
