Blood for analysis is most often taken from the ring finger. This is due to the fact that he is less involved in the work, in contrast to the index and average. The skin on it does not coarse, since it is rarely involved in any actions. The puncture is less painful. The little finger is directly connected to the shells of the hand. He is also unsuitable for drawing blood. There is a possibility of infection, and it spreads very quickly along the arm.
The strongest fingers in a person are the index, middle and ring. An adult with outstretched limbs of the arms can withstand a weight of 55 kg, much more in a bent state.
Throughout life, a person bends his fingers about 25 million times.
The Finnish, Tatar and Persian languages also call the ring finger. Experts believe that this phenomenon is due to faith. They are convinced that the finger is endowed with magical properties, therefore it is forbidden to call it by name.
The custom of using fingerprints as identification dates back to antiquity and has survived to this day. This is how illiterate people of all times and peoples leave their imprint on documents instead of signing. And in Japan, instead of printing, prints of the 1st and 3rd fingers are left on especially important documents.
The newly taken fingerprint weighs only 0, 000001 g. It contains fat, salt, proteins and water, which are secreted by the skin and the paint itself.
Fingers are one of the most sensitive parts of the human body. They have the ability to pick up vibrations with an amplitude of only 0.002 mm.
On the legs, only the thumbs have the name. For the rest, nothing definitive was invented
A rare mutation in the SMARCAD1 gene can lead to adermatoglyphia, a genetic disorder that results in a person's lack of fingerprints. Currently, worldwide, only 4 families are documented in which adermatoglyphia has been identified.
The misconception that the ancient Roman spectators in the Colosseum chose life or death for the vanquished, pointing their thumb up or down, arose after the appearance of the painting ‘Pollice Verso’ by artist Jean-Léon Jerome, who had little knowledge of Latin culture. In fact, a thumb bent in any direction meant death for the vanquished, symbolizing a drawn sword. And in order to bestow life, they showed a clenched fist, hinting at a sword hidden in a scabbard.
During the Hundred Years War, the French cut off the middle and index fingers of captured English and Welsh archers. Thus, they could not use a bow for shooting. Later, the victorious British began to show the French the presence of the middle finger - this is how the notorious "fuck you" gesture appeared. And his middle and index fingers in the form of the letter V - "viktory" or "victory".
