ABOUT THE USE OF THE FAMOUS 'SINGLE PALMAR CREASE' AS A NOTORIOUS MARKER IN HAND DIAGNOSTICS
Usually in the human hand appear 3 strong major lines (in medical science: 'palmar flexion creases') on the palms of the hands. These lines are known as: the life line ('radial longitudinal crease'), the head line ('proximal transverse crease'), and the heart line ('distal transverse crease'): see the left hand below.
But sometimes, the 2 horizontal lines - the head line & the heart line - appear to be COMPLETELY fused into a single line, which usually covers the full palm from the region between the thumb and index finger, to the region below the little finger: see the right hand below.
A 'complete' simian line can be recognized by a combination of 5 typical characteristics.
Five hand characteristics featured with a 'complete' Simian Line:
1 - One of the 2 normal major horizontal creases appears to be missing!!
2 - The simian line origins in the life line (sometimes at a slightly higher point);
3 - The simian line progresses the full palm as a strong line, without making 'splittings' or 'sharp angles';
4 - The simian line reaches the other side of the palm (below or close to the palmar knuckle of the little finger);
5 - There is no other (likewise strong) horizontal line which ends at side of the palm below the little finger.
NOTICE: If a line is 'suspected' to be a simian line but shows only 4 of these five characteristics, it usually will turn out... not to be a 'complete' simian line!
Photos below are examples of a 'complete' simian line ('click' for larger version):
The basic characteristic of this variant is that it appears to have far most aspects of a 'complete' simian line, but here the heart line & the head line are (only) PARTLY fused!! Often this variant are featured with a clear 'splitting' of the line, which can be associated with for example: the distal part of a heart line, or the proximal part of the head line. A likewise variant concerns a hand which appears to be featured with a complete simian line... plus> other clear line(s) that can be associated with the presence of a dissociated partial heart line or -head line (or both).
Because of these characteristics, the 3th characteristic of the 'complete' simian line can usually not be applied to an 'incomplete' simian line.
NOTICE: Regarding hand diagnostics the 'incomplete' simian line is usually treated likewise as the 'complete' simian line.
Photos below are examples of an 'incomplete' simian line ('click' for larger version):
Beyond the 'complete'- & 'incomplete' simian lines there are a few hand lines that could easily raise associations with the simian line. One of those hand lines are the 'bridges' between the heart- and the head line.
However, one should know that these 'bridges' are found in the hands of many people. And in far most of these cases these bridges are rather fine lines, while both the heart line and head line are actually perfectly normal! Actually, especially when a hand appears to have many bridges, a closer study reveals that often these fine lines show a path that appears to be unrelated to both the heart line and the head line. For, in many cases those fine lines may stop before they reach the major lines or they may actually cross one or both major lines. This shows a perspective which indicates that lines between the heart line and head line often do not serve as a true 'bridge' at all!!
So, in general, it would be wise to avoid associations between those common 'bridges' of fines lines and the rare simian line. Especially when those bridges are LESS STRONG than the major lines (heart line & head line), those minor lines should not be associated with the simian line at all.
How about a single, clear 'bridge' between
a complete heart line & head line?
There is only one type of 'bridge' which can be directly associated with a simian line. For sometimes hands may have a complete heart line + a complete head line, combined with the presence of likwise strong line that 'smoothly' bridges the heart line and the head line. If that 'bridge' is positioned like a raizor straight line into a part of both the heart line AND the head line, one can speak of a 'transitional' simian line.
Photos below are examples of a 'transitional' simian line ('click' for larger version):
But if the 'bridge' is positioned with a considerable 'angle' into the heart line (or head line), one can at most speak of a: minor simian line 'variant'.
As described earlier, the simian line may show up in many different shapes and related manifestations: starting with the (1) 'complete'- and (2) 'incomplete' simian lines, via the (3) 'transitional' simian lines, ending with the (4) minor simian line 'variants'!
Next to the example of 'strong but angled bridges' between the heart- and head line, there are 2 other relatively common examples of 'minor' simian line variants:
• the 'simian-related' heart line (a simian-like formation of the heart line, featured with a perfectly normal head line);
• and the 'simian-related' head line (a simian-like formation of the head line, featured with a perfectly normal heart line).
In the perspective of hand diagnostics such 'minor' simian line variants, should in general not only be recognized but also treated as a minor variant of the classic simian line!
Photos below are examples of (minor) simian line 'variants' - though the left example can also be described as a 'transitional' simian line ('click' for larger version):
• the 'Sydney line', an (underestimated) extended head line that transverses the complete palm (featured with a normal heart line);
• and the 'extended distal transverse crease', which relates to an extended heart line that transverse the full palm (featured with a normal head line).
