Why is a person s ring finger less flexible than the other four fingers?

The finger between the middle finger and the little finger is traditionally the least flexible finger in the human sense, because the ring finger is the weakest of the five fingers. See Mencius I "Now there is a nameless finger, and I can't believe it. "Faith is the same as "stretch".

It means that the ring finger is bent and cannot be straightened, and it does not mean that the qi is weak. [Why is the free movement ability of people's ring finger poor? In daily life, most of the activities carried out by human beings are done by hand, and the thumb and index finger are the most frequently used among the ten fingers, and the other fingers are only auxiliary.

So the thumb and index finger have a lot of flexibility. If you bend your index finger and ring finger back and forth with the middle finger as the axis, you will find a big difference in their amplitude. You will find that only the upward angle of the index finger is the largest, while the little finger is the smallest.

From the point of view of the distribution of fingers, the middle finger and the ring finger are in the middle of the five fingers, which are disturbed by the other fingers at both ends, and it is inevitable that the two fingers are inseparable or difficult to separate when the other fingers are close together. At the same time, because the little finger has a greater influence than the index finger, the ring finger is more difficult to separate than the middle finger or cannot be separated at all. There are deep anatomical reasons for this.

You can do such an experiment. Bend your middle finger towards your palm, and then place your palm against the table, as if only your middle finger is "kneeling" on the table, with the remaining four fingers supported. Then you can try to lift your thumb, index finger, ring finger and little finger, and you will find out:

With the middle finger fixed (that is, when "kneeling"), only the ring finger cannot be raised! This is because among the tendons that pull the fingers, the tendons of the thumb are independent, the tendons of the index finger are also relatively independent, and the middle finger, ring finger and little finger are first connected to a tendon, that is, the tendon symphysis. Among them, the tendon symphysis of the ring finger is the largest, so his movement needs to be restricted by the middle finger and little finger, to put it bluntly, if he wants to exercise, he has to mobilize the middle finger and little finger to move with him, so the flexibility is the worst!

With the middle finger fixed ("kneeling"), the ring finger cannot be lifted in any way!

The movement of the ring finger is limited to the middle finger because the ring finger does not have its own independent extensor muscle, which is the tendon that we can feel, and the ring finger and middle finger share an extensor muscle, and the middle finger and ring finger must be used to share the extensor muscles. This muscle is used to stretch all fingers except the thumb. If you want to extend the ring finger, the flexor muscles of the middle finger have to contract, which actually constrains the middle finger, and the extensor muscles of the ring finger and middle finger cannot work.

If the middle finger and ring finger are extended together, it is easier because the flexor muscles of the middle finger are no longer in the way of extension. When we make a fist, it's easy for the other four fingers to open completely individually, but not the ring finger, which my piano teacher told me and I've demonstrated over the years.

If you clench your fist or release it, you can see that all your fingers are moving together in harmony. If you try to control the movement of a single finger, the situation is very different. Try a move like this:

Start with a fist and try to straighten each finger individually. Also, try straightening all your fingers a little more and bending each finger individually. During this process, you should note that controlling the movement of the ring and middle fingers alone is the most difficult.

Ring finger and middle finger – These two fingers do not have independent flexor or extensor muscles, they share muscles with the other three fingers. When you try to bend or straighten your ring and middle fingers, the other fingers will have the same tendency, making it difficult to control their movements alone.

This is a false perception, unless it is a congenital "loss of function" or "underdevelopment", resulting in inflexibility of the limbs, otherwise it is possible to increase flexibility through exercise, the "ring finger" of human beings.

Compared with other fingers, the reason why it is not flexible enough, is not a congenital problem, among the five fingers of human beings, the least commonly used is the "ring finger", and human control over it is also the weakest, inflexibility does not mean "loss of function", these are two concepts, targeted exercise, can increase its flexibility.

Human beings have a total of ten fingers, every five are a hand, the fingers are located at the end of the hand, relying on the palm, wrist, arm and human shoulder to connect, taking the right hand as an example, from left to right are the thumb (thicker), index finger, middle finger, ring finger, and the left hand and the right hand are "mirror distribution". Human fingers are formed during the last three months of pregnancy, at the same time as organs such as the brain and heart, and the length of the fingers changes with age and changes in the body, but the ratio of the entire palm (finger) does not change with the change of the body. That is, from birth, our finger ratios are fixed.

The activity of the fingers itself depends on the nerves, ligaments and muscles, and the bones play a supporting role, in the process of human embryo formation, the palm is formed first, and the fingers are formed on the basis of the palm, and there will be adhesions, similar to the fins of fish.

Like duck webs, these "webs" will gradually disappear during the continuous development of the embryo, and in this process, the bones, ligaments, muscles, nerves, blood vessels, etc. distributed on the palm of the hand will be further formed, including 29 bones, 123 ligaments, 35 muscles, 48 nerves, more than 30 arteries, and densely divided small blood vessels and capillaries.

The capillaries distributed at the ends of the fingers are one of the densest areas of the human body). The reason why human fingers can move is that the brain sends signals to muscles and ligaments through nerves to drive bones (specially structured bones) to move.

Taking normal people as an example, the fingers of normal people after the development and growth of pregnancy (embryo) are basically the same after birth, but due to genetic and congenital reasons, even if two infants with normal function, their control of finger flexibility is different. In addition to some congenital diseases, most children are born, with the increase in activity, the frequency of finger use, finger flexibility will become better and better, but relatively speaking, human beings use the thumb and index finger most frequently, followed by the middle finger and little finger, and finally the ring finger, and this is the main reason why the flexibility of the ring finger is weaker than other fingers.

Conclusion: If you want to make the ring finger as flexible as other fingers, you can carry out targeted exercises through "finger exercises", the flexibility of the fingers is related to the sensitivity of the finger nerves, ligaments, and the strength of the muscles, and the sensitivity of the nerves, ligaments and muscles can be increased through special exercises, and the ring finger can naturally become flexible, as long as it is not a congenital "loss of function", after a period of exercise, you can also have the flexibility of not less than the other four fingers.

It has been theorized that the reason for the inflexibility of the ring finger may not be in the hand muscles, but in the brain, and it is used minimally. And the ring finger is the finger with the least strength among the five fingers.

Mainly because humans use the ring finger relatively rarely, the ring finger is the least flexible.

Because in ordinary life, our use of it is relatively small, and he only plays an auxiliary role, so the words are the least flexible.

It seems that it is because the muscles that control the ring finger are long and difficult to stretch.

Because the human ring finger itself has not been used much, after thousands of years of inheritance, the ring finger of our descendants is not flexible!

Some people are born, that is, the genes of their parents. Some people are trained. Are you learning a musical instrument? Then which finger is not good, which finger is specially practiced.

Cut your middle finger and don't move. Hehe, this is the reason for the structure of the human body.

The ring finger is the finger between the middle finger and the little finger, and it is the most inflexible finger in the traditional sense of the human bridge, and the ring finger is the finger with the least strength among the five fingers. Hand filial piety is the five branches of the front end of the human hand, generally there are five branches: thumb, index finger, middle finger, ring finger, and little finger.

Fingers are formed during the last 3 months of pregnancy, which coincides with the formation of the baby's brain, sexual organs, and heart.

The strength of the ring finger is deeply related to a person's overall health, so the Japanese also call it "medicine finger". It is used as a reference for medical treatment.

The ring finger is generally the finger used to wear a ring, and after marriage, it will turn a person from a nameless to a name, so it is called a ring finger.
