Why do human fingers keep bending?

Hehe, this boy is so humorous, what you said is quite reasonable, let me add, why are the fingers bent in space. When the fingers are straightened or the fist is clenched, there is always one side of the skeletal muscle that will contract, so as the person above said, in order to save energy, people will instinctively let the organs that do not work at a low energy consumption level in the process of evolution, so just bend the fingers, and the skeletal muscles on the palmar and dorsal sides do not have to contract hard.

As for why it consumes the least energy when bending, it should be because the initial length of skeletal muscle on the palmar side of the finger and the dorsal side is different. The initial length is the original length of the skeletal muscle before contraction. Imagine that there are two rubber bands of different lengths on both sides of a piece of bamboo, and the bamboo piece will definitely bend

Seeing your **, you can consider 3 problems, first, dislocation of the knuckle after trauma, unreduced deformity; Second, after trauma, the extensor tendon rupture of the finger brevis was not surgical; 3. Some people's flexor tendon elasticity is super good or lacks function, and it can be hyperextended, especially in thinner girls and boys, which is a normal phenomenon. If it doesn't affect your life and doesn't affect the function of your hands, you don't need to pay attention. If it is inconvenient for you to live, work, or study, you can go to a regular hospital to consult an orthopedic surgeon.

The answer is found, Lang Lang's fingers are similar to yours, and there is a term called "piano player". If you don't have symptoms and don't affect your life, study, or work, you don't have to do it!

Landlord, I am very curious about your curiosity. As for the question you raised, I think it's more appropriate, because there are two phalanges in each of the fingers, and because of gravity, one of the phalanges must droop, so the fingers are curved, just like the legs of the people. If there is only one phalange in a person's finger, then the person's finger will not be bent, hehe.

Because only bending is the most effortless.

Requirements: Fingers touch the key with the fingertips, except for the fingertips, the other fingertips are at a 90-degree right angle and lean back a little bit at the basic vertical angle. When touching the key, the small joints at the tip of each finger should stand upright, forming an arc shape that supports outward.

Principle: When playing the piano, the fingers must have a certain hardness to play the sound to be strong and powerful, and the fingertips must have hardness, the finger joints must be upright as collapsed, the fingers will be soft and weak, and the sound will not be strong. That's why the facet joints of the fingers are erect.

When playing the piano, the shorter the fingertip touches the keys, the longer the vibration of the piano sound. If the fingers are bent when playing the piano, the fingertip reaction will be more agile than the finger straight, and the touch time will be shorter than the finger straight, which is another reason for the finger to be bent.
