When the left shoulder is stirred, there will be a tendon stuck, with a bang. I'm sure it's not the sound of bones. What happened?

The "click" sound of some body parts is actually the click sound of joints, which refers to the sound made by the joints of the human body during exercise.

Why do bones ring?

First of all, the bone sounds, so don't be afraid.

Some people's fists and joints will ring, which is caused by friction between bones.

There is lubricating liquid between the joints, which has lubricating effect and the texture is as smooth as egg liquid. Its main function is to cushion the impact between bones. Whether people walk or exercise, as long as they move, their joints will move with them. This lubricant can play a buffering role. The main components of joint lubricating fluid are water and a lot of nutrients. In addition to lubrication, it can also discharge bone and cartilage debris inside the joint.

When we make a fist or use force, the gap between joints will become larger, but the amount of lubricant is still the same. At this time, the joint will produce a low pressure area, which will lead to the release of bubbles, so the bone will ring.
