Knowing what your bones do might help you understand what bone cancer is.
Bones are like human scaffolding.They help keep us upright. The human skeleton is made up of more than 200 bones of different shapes and sizes.
Bones do lots of important things:
- They work together with our joints and connective tissue so that we can move around.
- They protect parts of our bodies from injury -for example, the ribs protect the heart and lungs.
- They store calcium.
- Some bones contain bone marrow, which makes our blood cells.
Joints help bones fit together so that we can move freely. There are different types of joint. Some work as levers, like the finger joint. Others are ball-and-socket joints, such as the hip joint.
There are different types of connective tissue that help bones move:
- Ligaments are tough cords of tissue that attach bones to each other.
- Cartilage is a slippery material that covers the ends of bones to stop them rubbing together.
- Muscles are made of tough, stretchy tissue. Muscles give us our strength.
- Tendons are strong cords of tissue that attach muscles to bones.
