Exercise can often hear someone make a "rattle" sound, such as the knee joint when squatting, the hip joint makes a gentle "rattle" sound when walking, the neck turns the cervical spine has a sound, and the fingers are clenched to hear the sound ...... fingersThese sounds are often referred to as "popping".
Generally speaking, people who only have a snapping sound, do not feel redness, swelling, or pain, and are not accompanied by mobility disorders are physiological snappings that do not require special treatment or need to be too anxious. When a joint is moving, there is always friction between the articular surfaces, between the cartilage pads and the articular surfaces, and between the tendons and joint capsules. In most people, this sound is not noticeable, while in others it sounds more distinct.
Especially for those who sit for a long time, there is less lubricating fluid between the joints, which increases the loss of friction in the joints, and it is easier to hear the snapping.
When accompanied by pain or limited joint movement, a visit to the hospital is needed to determine if the joint is misaligned or damaged. People like teachers, secretaries, computer entry clerks, etc., who work at desks all year round, often complain about the "popping" of the cervical spine, which reminds people not to maintain the same position for too long, but to exercise more. It is best to get up and move a little for 15-30 minutes.

1. Don't be afraid of pain for the first time, first pull your fingers with your left and right hands, so that they will generally ring. Then get used to breaking it after two days, make a fist with one hand (don't clench), press its joints with the thumb with the other, and repeat it a few times to easily break the fingers.
2. The reason why the finger joints make the joints rattle is that the gas dissolves due to the increase in the inter-joint space, and produces tiny bubbles in the synovial fluid of the joints, which gradually merge into large bubbles, and produce a rupture sound when more body fluids flow to and fill the enlarged space.
3. I advise you not to develop the habit of breaking your finger joints, if you have this habit, it is best to get rid of it in time, otherwise once the damage to the finger joints is formed, it is irreversible, and it will lead to a misstep into a thousand years of hatred.

Mine can, don't be afraid that it will break, it rings very little at first, but slowly it will increase, 8 of my 10 can ring, and the two little fingers dare not get it, it's too thin.

1. Make your hand in the shape of an orchid finger, bend the ring finger and little finger against the palm of your hand, and contract your index finger close to the middle finger.
2. Let the thumb and middle finger hit each other hard at the same time, that is, the thumb moves outward and the middle finger moves inward.
3. Because the thumb and middle finger move towards each other at the same time, friction will be generated, and due to the small contact area and large force, the air flow will collide and make a sound.
4. The index finger does not have to be close to the middle finger, but it can also be bent against the thumb, and the sound of snapping the finger is louder after bending.
5. If the fingers are slippery, the sound of snapping the fingers will not sound when dry, and the fingers can be moistened with water.

1.Preface.
As we all know, snapping fingers is a common sound, especially in some ceremonies, performances, or occasions, and is often used to show approval or applause. But, do you know why snapping fingers make a sound? Today, this article will introduce the principle of snapping fingers to make sounds.
2.The principle of sound production.
To understand how finger snapping sounds, early blindness first requires an understanding of how sound is produced. Sound is produced by the vibration of an object, and when the object vibrates, the surrounding medium also vibrates, thus forming sound waves. And these sound waves eventually travel to our ears so that we can hear sounds.
3.Why does snapping fingers make a sound.
Next, let's take a look at why the early snap fingers make a sound. The sound of snapping fingers in the air is caused by the impact sound caused by the rapid slapping of two fingers. When two objects collide, some special physical phenomena occur, such as the generation of sound waves, which produce sound.
4.The sound principle of snapping fingers.
Specifically, the sound principle of finger snapping is as follows: when we quickly shoot with the index finger and middle finger, the middle finger hits the second joint of the index finger, and at this time, a vibration is generated, and the surrounding air also vibrates, thus forming sound waves. When these sound waves reach our ears, we can hear the snapping of our fingers.
5.Snapping fingers to make a sound.
In addition to a quick tap, snapping fingers also requires certain conditions to make a sound. For example, fingers need to be kept dry, as wet fingers can reduce friction between the two fingers, which can affect the generation of sound waves. In addition, the spacing between fingers needs to be appropriate, and generally speaking, the interval between the fingers is about one centimeter.
6.How to snap your fingers louder.
If you want to make the snapping sound louder and clearer, there are a few tricks we can use. For example, the strength of the fingers should be strengthened appropriately to ensure that the impact of the two fingers is more powerful; Or rub your fingers together to make them warm so that there is more friction between your fingers, resulting in stronger sound waves.
7.Epilogue.
In summary, the snapping of fingers occurs due to the impact sound caused by the friction between the fingers. The sound of snapping fingers is also not completely random and requires certain conditions and skills. By understanding the principle of sound produced by snapping fingers, I hope to give you a deeper understanding of the nature of sound and apply this knowledge to real life.

Take the right hand as an example, 1Press your thumb firmly on your middle finger while your little and ring fingers bend in a natural state, with the tip of your ring finger resting against the base of your thumb, the part of the chicken leg that has the most meat.
2.The thumb and middle finger are forcefully hitting each other in the opposite direction at the same time, that is, the thumb goes in the direction of the index finger and the middle finger goes in the direction of the ring finger.
3.The middle finger hit the gap between the bottom of the ring finger and the thumb (that is, the chicken leg position), and the air that pressed the gap occurred**, causing a human air hydrogen bomb explosion, commonly known as"Snap your fingers".
4.In fact, the ring finger does not have to be bent to hit the snap finger, and the middle finger will make the same sound when it hits the chicken leg of the thumb, but it is loud when the ring finger is not added.
When the fingers are clicked, the middle finger and thumb are applied in opposite directions. This exerts a force in the opposite direction to the middle finger, making the middle finger strike harder. The impact of this force caused the air near the ring finger and little finger, which had been placed in the palm of the hand, to suddenly accelerate.
In addition, there is a sound of rubbing between fingers.
Practice a little more, and wash your hands when you feel unconfident. When there is water in the hand, this friction will increase and be louder than the normal finger clicking. Maybe you will be in the water.

When you clutch or pull your fingers, the knuckles make a sound, called "joint popping".
The snapping of the knuckles is caused by friction between the articular surfaces, between the cartilage pads and the articular surfaces, and between the tendons and joint capsules.
Some people don't have a noticeable sound, while others sound it more clearly, especially those who are sedentary and less active, and less lubricating fluid is produced between the joints, which increases the friction of the joints and makes it easier to hear the snapping sound.
If the joint only snaps, the appearance is not red or swollen, there is no pain, and there is no impaired mobility, it is a physiological snap and does not require special treatment.
In general, joint ringing in young people is mainly due to physiological causes; In older people, once the joint sounds, it is more important to consider whether there are local lesions, such as ligament strain, bone spurs, etc. In this case, it is necessary to go to a regular hospital for examination as soon as possible to find out the real cause.
It should be noted that gentle, regular knuckle movement is beneficial, but excessive, rough movements, such as frequent and forceful tugging on joints to make noises, can cause damage to the joints, so the bad habit of pulling the fingers should be overcome.

Answer: The sound of the finger joints is mainly caused by abnormal friction of the cartilage in the finger joints. This condition is mostly seen in the following two reasons: First, the degeneration of the finger joints, which causes the tightening of the surrounding ligaments and joint capsule, as well as the degeneration of the internal cartilage.
When the fingers move, it causes abnormal friction of the cartilage inside, which causes the joint sounds of the fingers. 2. Seen in rheumatoid arthritis, rheumatoid arthritis mainly erodes the small joints of the hands and feet, resulting in obvious swelling and pain in the facet joints, and it is easy to lead to deformity of the facet joints in the later stage, which will also cause abnormal friction of cartilage when the finger joints are active, resulting in the appearance of finger joint sounds.
The purpose of the test is to: 1. Test the examinee's mastery of a certain aspect of knowledge or skills; 2. Check whether the examinee has the basic ability to obtain a certain qualification. Examinations are a two-way response, one is to reflect the effect of students' learning over a period of time; The second is to reflect the results of the knowledge taught by the teacher.
Students should face the exam positively, regard the exam as an opportunity to show their learning ability, put the score on the back burner, and take every question seriously. The results of the examination in which the teacher treats the student should not be judged by the results of the examination. Instead of putting too much emphasis on the scores, you should carefully analyze each question in the dismantled test paper, so that students know that they should improve and that they should continue to maintain.
