Under our skin is a skeleton made up of bones.

A skeleton is all the bones of the body joined to ligaments and tendons that form a protective cover for body organs such as the heart and lungs. There are 206 bones in the human body.

Bones are hard on the outside. Inside they are soft but strong. Red and white blood cells are made inside bones from bone marrow. Bones also store minerals that the body needs. They are made of protein, minerals, and vitamins.

The tiniest bone is inside the ear. It is just 3 millimetres long.

This is an X-ray of a hand. An X-ray is a photograph of the bones inside the body. The hand is the part of the body with the most bones. There are 27 of them in each hand.  There are 26 in each of your feet!

A joint is where two bones meet. There are different kinds of joints. Some bend in only one direction, like a knee or elbow. Some move in all directions, like a hip or shoulder. Some turn, like a neck or wrist.

Good food and exercise make bones strong and healthy. Eat plenty of fresh fruit and vegetables, drink milk and eat nuts and cheese. Walking, climbing and dancing  are good exercises for building strong  bones. So are team games such as football and basketball.
