Bones On
the Go!
Let’s
get down to the bare bones: You need your skeleton. The skeletal system, or framework of bones, doesn’t just hold you up.
It gives your body its shape, protects your organs, and works with your muscles
to help you move.
At
birth, you had more than 300 bones, which fused together as you grew. By the
time your body is finished growing, you’ll have about 206 bones. Researchers at
Wright State University School of Medicine in Ohio have discovered that kids
who exercise have stronger bones as adults.
Your
body has plate-like bones that cannot move, such as those that make up the cranium. The cranium protects your
brain.

The
stirrup bone, also called the
stapes, is in the ear. It is the smallest bone in human body.
|
Your
body is made up of many movable bones, such as the humerus, which is located in the upper arm.
|
Your
ribs provide a protective casting
for important organs, such as your heart and lungs.
|
The
spine is made up of 33 bones called the vertebrae.
|
The
thighbone is called the femur. It’s
the longest and strongest bone in your body.

How
else can you bone up? Make sure your body gets enough calcium. That bone-building mineral is found in foods and drinks
such as yogurt, leafy greens, and milk.
