Cracking your knuckles releases the nitrogen from in between your joints.
This noise, unless, painful, is due to air in the joint. See link below about joint popping.
I'm guessing by clicking you mean the sort of popping action people do when they sort of push their knuckles. This is completely harmless in the long term and will not misshape you fingers, make your fingers shorter or give you arthritis. It's all just an urban myth. When you do click your fingers or pop your knuckles the sound isn't the bone cracking or hitting against another bone, it's simply a small bubble of trapped air which squeezes its way free through a small space. Kind of like poking a balloon with a pin. It creates a small hole and all the air tries to escape at one making a bang. That's all it is. Nothing damage, nothing to worry about. Unless you do it too hard and break something :P But that's not likely to happen.
If popping can be heard in the finger, it is possible it is only cracking the air bubbles; however, if popping can be heard as well as the finger causing pain with noticeable swelling, it is likely it is dislocated.
The ribs expand so that we can breathe. When the ribs expand, the volume of the pleural space increases and the lower pressure brings in air.
Answer - Air Force, as per:Joint Publication 3-30,Command and Control of Joint Air Operations, 10 February 2014:"The JFC will normally assign JFACC responsibilities tothe component commander having the preponderance offorces to be tasked and the ability to effectively plan, task,and control joint air operations. However, the JFC willalways consider the mission, nature, and duration of theoperation, force capabilities, and the C2 capabilities inselecting a commander."component commander is another way of saying the commander of a unit with in the military service type (Army, Navy, Marine, Air Force, et cetera)
Most people say cracking knuckles leads to arthritis. It doesn't! I wouldn't recommend cracking your fingers all the time, and I personally don't like cracking fingers in the cold. You can, if you want to, but it hurts. I think the weather of the cold air affects the finger joints which make them stiff and harder to crack. Cracking your fingers also open your joint air holes, so you'll be okay. Cracking fingers are mostly fine to do!!
Air bubbles, same as in cracking knuckles...
No all it does is make an air bubble at the joint of your bones. It makes no affect whatsoever on your hand size. Your hand size is all determined by your genetics.
I've been cracking my knuckles, back, neck, knees, etc. for years now and my doctor tells me it's tiny air pockets. He said as long as it doesn't hurt, it's perfectly ok to continue cracking joints.
Cracking your knuckles is just releasing the nitrogen in between your joints. Cracking your knuckles can cause you to crack them more often. Your knuckles may become larger from cracking them.
What's really happening when you "crack" your knuckles:The noise you hear is actually the creating of small bubbles of nitrogen. This is an absolutely harmless thing to do despite all the "old wife's tales" to the contrary.
This noise, unless, painful, is due to air in the joint. See link below about joint popping.
No. The cracking sound is caused when the small bubbles of air in between your joints pop. It does not cause any problems. People who say that is causes damage are passing on a myth.
The risk of cracking one's knuckles (sliding joints under pressure) is that it can cause inflammation of the joints, or even cartilage damage. In young people, this damage will usually be repaired in a short period, but it could aggravate arthritis in older adults.
No. The pop is caused by a partial vacuum being created in the joint, which is quickly filled by fluid and air.
popping air bubbles trapped in your joints. Forcing so joint to crack however can cause problems later in life
If air has been introduced under the skin, it could cause a popping-crackling sound after surgery. The patient should bring this to the attention of his or her physician. Typically, these small air bubbles are re-absorbed by the body but the surgeon should be made aware so the area can be assessed.
