The skeletal system

How does the Skeletal System Work?

 

The skeletal system is a group of bones that work together to move your arms and legs.

 

First the brain tell your nerves to move your muscles, then the muscles move your bones.Your bones have joints to help them move.

 

The thigh bone is the longest bone and the strongest bone in the body. The smallest bone in your body is called the stirrup. This bone helps you balance when you stand.

 

You actually had 300 bones when you were born. As you grow up your bones fuse together. There are 206 bones in the adult body.    by Iris
