Bones-made from elements phosphorus and calcium
206 bones in average human. Newborns have more (some have not fused yet!)
Smallest bones are in the ear—Hammer, anvil, and stirrup
Largest bone is the femur (thigh bone)
5 major functions
unique structure for each organism-skeleton provides the framework while supporting the body and the organs within
Muscles are attached to the skeleton. The muscles contract, pulling on the bones. The attachment to the bone allows the movement or contraction of the muscles. Just like a rubber band cannot contract unless it is attached at both ends.
