Interesting Bones Facts

September 17, 2009 | In: Medical facts

The smallest bone in the human body is the stapes bone which is located in the ear.

Although the outsides of a bone are hard, they are generally light and soft inside. They are about 75% water.

A total of 54 bones are found in both of your wrists, hands and fingers.

The longest bone of the human body is the femur or thigh bone, which comprises roughly 1/4 of the persons overall height.

Kids have about 100 more bones in their bodies than adults do. (Adults have 206 bones; kids have about 300.)

What happens to the extra bones as you grow up? They join together, to make bigger, stronger – but fewer – adult bones.

Having more but smaller bones helps kids be more flexible than adults – which is one reason why tumbles, jumps, and flips are easier for kids than for grown-ups.

A broken bone will take about 12 weeks to heal.

Bones can continue to grow until you are 30 years.
