**The backbone **


 * The backbone or vertebral is really a flexible structure made of 26 bones. **
 * As a baby you have 33 vertebrae. but the lover four fuse to forn the coccyx-sound, and **
 * the next lower five fuse to become the cacrum. the backbone sirves seferal important **
 * functions itself. it provides structure from witch all other upper body structures **
 * branch, and it protecs the spinal nerve, which is the "highway" that all the information **
 * your brain sends to your body travels. if the spinal column were to ne dameged it would **
 * be like the highway collapsed, and all the landmarks past that point could no longer be **
 * visited, causing paralysation from that point in your back and down. **

 * the appendicular skeleton refers to your arms and legs. they are called appendicular because they areattached **
 * by girdles, which bridge each with the main body, as if they had been appended after the main body was formed. **
 * these girdles give these appendages a ramarkable range of movement unique from anywhere else in the body. **
 * obviously the arms are the same allowing symmetry, and the legs are too. but ignoring size and shape, and instead **
 * focusing on joints and relative placement, your legs and arms are the same. **
