Why do your joints pop?

Answer 1

It's not the bones the pop. Sometimes you get little air pockets in the tissue that is between your joints and that is what causes the pop sound.

Joints are the meeting points of two separate bones, held together and in place by connective tissues and ligaments. All of the joints in our bodies are surrounded by synovial fluid, a thick, clear liquid. When you stretch or bend your finger to pop the knuckle, you're causing the bones of the joint to pull apart. As they do, the connective tissue capsule that surrounds the joint is stretched. By stretching this capsule, you increase its volume. And as we know from chemistry class, with an increase in volume comes a decrease in pressure. So as the pressure of the synovial fluid drops, gases dissolved in the fluid become less soluble, forming bubbles through a process called cavitation. When the joint is stretched far enough, the pressure in the capsule drops so low that these bubbles burst, producing the pop that we associate with knuckle cracking.

It takes about 25 to 30 minutes for the gas to redissolve into the joint fluid. During this period of time, your knuckles won't crack. Once the gas is redissolved, cavitation is once again possible, and you can start popping your knuckles again.

Answer 2

typically your ears pop when they undergo pressure of somesort. for intstance, when you go up in an airplane your ears pop due to altitude pressure and the air lock system in the plane. when you go diving your ears tend to pop because of all the water pressure being placed on your body.

Answer 3

due to trauma and degenerative changes. In a healthy person sometimes joints just pop. Synovial joints make fluid to ease movement and the fluid degrades and emits gasses and makes a popping noise

The Synovial joints of the body are normally bathed in synovial fluids and are generally pretty well contained. this leads to a situation where there is a degree of pressure in and around the joints. if the joint is moved in such a way as to cause this pressure to be reduced gasses such as nitrogen and carbon dioxide are released from the fluid causing the poping/cracking noise. the principle is similar to what happens when opening a bottle of soft drink.

Answer 4

Healthy joints are a tightly fitting unit, joints covered with cartilage and these are then surrounded in synovial fluid to lubricate them. when the joints are puled or forced apart slightly as happens When the right pressure is applied to a joint, the area inside the joint capsule expands. However, the expansion is limited by how much synovial fluid is contained in the joint. Synovial fluid cannot expand unless pressure inside the joint capsule drops and the dissolved gases can escape out of the fluid. The cracking sound comes from the gases, dissolved oxygen, nitrogen, and carbon dioxide rapidly being released from the fluid in much the same way as a bottle of soft drink releases Carbon dioxide when you open it.

Answer 5

There are gasses dissolved into the sinusoidal liquid that the joints are bathed in (sort of like the gas in a cold ice soda, but much more dissolved that that). When you over-stretch the join, the cavity between the joints increases causing a decrease in pressure and so the gasses in the joints precipitates out (kind of like when you open a new can of soda and the gas hisses out). The sound you hear is that gas escaping the joint. It takes about 30 or so minutes for the gasses to dissolve back into the liquid.

Answer 6

Your finger hurts because it might be broken

Answer 7

Our ankels pop because ot is letting the bone release and pops it insteads of breaking it.
