What causes knuckles to making popping sounds?

The video explains how gases in synovial fluid expand and burst, causing a popping sound when knuckles are cracked. This process stimulates nerves and relaxes muscles, often increasing mobility. It takes about 25 minutes for gases to rebuild in the synovial fluid before knuckles can be cracked again.

What causes the popping sound when knuckles are cracked?

• Muscles contracting

• Bones rubbing against each other

• Nerves being stimulated

• Gases expanding and bursting

How does the popping sound affect the body?

• It increases muscle tension

• It decreases joint mobility

• It stimulates the nerves and relaxes the muscles

• It causes pain in the joints

What is the result of the muscles relaxing after knuckle cracking?

• Joint pain

• Muscle fatigue

• Decreased flexibility

• Increased mobility

How long does it take for gases to rebuild in the synovial fluid?

• 30 minutes

• 25 minutes

• 15 minutes

• 10 minutes

What must happen before knuckles can be cracked again?

• Muscles must contract

• Nerves must be stimulated

• Gases must rebuild in the synovial fluid

• Bones must realign
