본문내용

A human being is a complicated collection of bones and muscles, and brain. Controlling everything is the brain, with more intelligence than that any other animal. What’s really amazing is how all this complexity starts as a single cell – a fertilized egg. But this cell is not so simple. Packed into its center-the nucleus-is everything needed to make a human body. Once the body is made, it takes years to grow and develop into a finely tuned machine that can reason and move anywhere its brain tells it.
Skeleton is a lot more than a collection of bones. Like the steel girders of a tall building or the truck and branches of a tree, it forms the framework for body. It gives a shape, and supports body’s weight, and anchors muscles so people can move. It is strong enough to protect delicate internal organs, such as heart, lungs, and brain, and yet light enough to allow him jump, climb, and swim. Form the skull to the toes, the adult human skeleton contains 206 bones and weighs about 9kg. A body’s skeleton contains 350 bones, but these are soft and fuse together as the body grows. The skeleton is not completely hardened and fused together until a person is about 30 years old.
