| The Skeleton is the name given to the collection of bones that
holds the rest of our body up. Our skeleton is very important to us. It does
three major jobs. |
| |
|
** It protects our vital organs such as the brain, the heart, and the lungs. |
|
| |
|
** It gives us the shape that we have. Without our
skeleton,we would just be a blob of blood and tissue on the floor. Yuck! |
| |
|
** It allows us to move. Because our muscles are attached to our bones, when
our muscles move, they move the bones, and we move. |
| |

|
| |
| When you were born, your skeleton had around 350 bones. By the
time you become an adult, you will only have around 206 bones. This is
because, as you grow, some of the bones join together to form one bone. |

| Our bones don't simply work on their own. The bones join
together to form joints. The end of each bone is covered by a tough, smooth
shiny substance called cartilage. The cartilage-coated bone-ends are kept
apart by a thin film of slippery fluid that works like oil in a car. All of
this is so your bones won't scratch and bump against each other when you
move. Our bones are held together by strong stretchy bands called ligaments. |
