DERMATOGLYPHICS – An introduction to the dermatoglyphs of the human hand!
January 26, 2010
The word ‘dermatoglyphics‘ was first coined by Harold Cummins in 1926, and refers to the study of the characteristics in the skin ridges of the hands and the feet. What are the most common dermatoglyphic characteristics?
In most populations around the world is the ‘ulnar loop’ the most observed fingerprint pattern (see: the fingerprint of the pinky finger in the picture above). Loops are most frequently found on the little finger (and middle finger); loops are least frequently found on the pointer finger.
The variations in the dermatoglyphics of the handpalm are much more complex than the variations in the fingerprints. An important element concerns the presence of the ‘palmar triradii’ (see: a, b, c, d, and t in the picture above): normally each finger is featured with a palmar triradius – triradius t belongs to the thumb (the thumb mouse – a.k.a. as the ‘thenar’, or in palmistry: ‘mount of Venus’ could be recognized as the third phalange of the thumb).
T = L + D – 1

Picture: example of a normal pattern of dermatoglypics [NOTICE: If the ‘c-line’ is ending between the ring- and middle finger it always creates a palmar ‘loop’, which implicates that the author of the picture has missed 6th palmar triradius between/below the c and d triradius]
