Well, I can, for example. I believe that I am not the only one so super-exclusive and that there are other similar craftsmen living in the world. So, I think that in general it is possible, just not everyone succeeds due to anatomy.
But this is not certain.
This can be done very well. All her life she could bend without even studying. Bending the little finger without bending the ring finger is easy. And so that the little finger fits the hand is difficult, NOYA MI. THAT AND ANOTHER I CAN
The question is worded incorrectly, bending the little finger without bending the ring finger is very possible, but pressing it to the palm of the hand without changing the position of the ring finger is difficult.
Isn't everyone able to do that?) Now I first learned about it. I flex my whole life on both hands, regardless of the other fingers. Wow, something must be wrong with me)
I can do it too. But she learned specially at the age of 7, reading "Reserve of fairy tales" by Kira Bulycheva:
"Alice learned the Martian language. The TV teacher spoke in a gentle voice:
I also learned on the left. What if this letter comes in handy too? :)
Why? Very much even possible. I even recorded a video, otherwise you won't believe it in words.
Although, here, on the right hand is no longer possible. Although, with proper practice, it can be on the right one too, I think.
This is where we need to refer to anatomy. Three muscles are responsible for bending the fingers of the hand: the deep flexor of the fingers (bends the distal, that is, the distal, phalanges of the four fingers - the index, middle, ring and little fingers); superficial flexor of the fingers (bends the middle phalanges of the above fingers). The muscle that flexes the thumb is shown separately (therefore, it is the most independent of all fingers on the hand).
Tendons extend from each phalanx of each finger to the corresponding muscle. These tendons lie in the vaginas with the corresponding names (for example, the little finger tendon sheath).
This is clearly shown in the following picture (the vaginas are drawn in blue):
So there is a separate vagina for the index, middle, ring fingers and for little finger (the thumb is generally off to the side - on its own). There is a common vagina (number 3 in the picture) where these tendons join. But the little finger has one feature: the sheath of its tendon is not independent, but is united with the common sheath of the tendons of the fingers.
Thus, when we bend the little finger, its tendon begins to pull along with other tendons in the common vagina. And most of all it pulls the nearby tendon (that is, the ring finger - it bends at the same time most of all), then the next (the middle finger bends weaker at the same time). This movement hardly reaches the index finger (so it barely bends when we bend the little finger).
