| What causes "popping" sound when you crack your knucles? |
|
Definition
1. when joint pulled tight, small ligaments or musles tighten and snap across bony protuberances of joint.
2. when joint pulled apart, air can pop out from between bones, creating vacuum that produces popping noise
3. when fluid pressure of synovial fluid reduced by slow articulation of joint, tiny gas bubbles in fluid may burst. |
