¿Qué pasa cuando crujimos los nudillos?

The video explains the phenomenon of knuckle cracking, where a noise is produced due to the formation and bursting of a gas bubble in the space between bones. Scientists are unsure why the sound is so loud. The bubble dissolves back to normal within half an hour. Frequent knuckle cracking can lead to joint inflammation and a reduction in grip strength.

What happens in the space between bones when a knuckle cracks?

• A ligament stretches

• A gas bubble forms

• A bone fractures

• A muscle contracts

What is the scientific explanation for the loud sound of a knuckle crack?

• The bones collide

• The skin snaps

• The gas bubble bursts

• The joint vibrates

How long does it take for the gas bubble to dissolve after a knuckle crack?

• 5 minutes

• 1 hour

• 15 minutes

• 30 minutes

What is a potential consequence of frequent knuckle cracking?

• Increased bone density

• Improved flexibility

• Joint inflammation

• Stronger grip strength

What percentage of grip strength can be lost due to frequent knuckle cracking?

• 75%

• 25%

• 10%
