Some people like the voices bang fingers while others repugnant, but scientists have long years different about what is causing it to be exact.
Researchers announced Wednesday that they have put their hands on exactly what is happening inside the joints to cause a bang fingers thanks to the magnetic resonance imaging experiments, which they called for joke "study tightening fingers," and said it became clear that the pop occur due to the cavity filled with gas quickly within tissues slippery substance called "synovial fluid" that facilitate movement in the distance between the phalanges of the fingers to occur pop in less than 310 parts of the A fraction of a second, and monitoring, the researchers also by the sound of pop straight white flash may have been caused by the rush of a small amount of water, and said " Greg Rubber "medical rehabilitation professor at the University of Alberta in Edmonton, Canada, who led the study, reported in the journal (PLoS ONE)" I love that sound. "
She says the first scientific study published in this regard in 1947, he turned out to be the voice of pop fingers caused by the gas inside the joint cavity, but other researchers rejected this interpretation in 1971, saying that the bubble inside the joint explosion was the cause of that voice, and in this new study, the scientists already strained the fingers of a man and then took pictures of the video process bang fingers through magnetic resonance imaging, which gives detailed images of internal body tissue imaging.
And contributed to one of the participants in the study, a "Jerome Fryer" and works in the field of orthopedic manually in these scientific efforts to insert his fingers into a tube connected to a cable was attracting his finger even bang finger occurred and said, "Richard Thompson" Professor of Engineering Bio medical University of Alberta "fast imaging resonance Magnetic typical in this type of study because it gives a very clear Bone and fluid surrounding the image and also the antenna cavity, "and added," I personally do not like the sound of pop fingers at all because I always imagine that the damage in the foundation of what is happening. "
He said, "Rubber" Some studies suggest that the pop fingers that does not cause any damage, and went on to say, "Why pop joints of the fingers occur in some people and talked to others? ... Wonder why the ability to become a pop joints someone sign that already detailed sound and lack of ability to do so may be an indication of problems with the detailed future? "
