Why do we break our knuckles and where does the sound comes from?

The knuckle joint is called the “ball and socket” joint or the synovial joint. The space between the two bones, which form the joint, is filled with the synovial joint. The space between the two bones, which form the joint, is filled with the synovial fluid. During metabolism, bubbles of carbon dioxide accumulate in the fluid.

When we break our knuckles, these bubbles break, making a sound. We twist and break our knuckles when the joints are strained. It takes about 10-15 mins. for the bubbles to accumulate.
