The skeleton shapes and supports the body, allows it to move, and protects internal organs. It is constructed from 206 bones that, far from being dry and dusty, are moist, living body parts. Together, those bones create a framework that is strong but light.
Without a skeleton the body would collapse in a heap. Yet it is not a rigid structure. Flexible joints between bones allow the body to move when those bones are pulled by muscles. The skeleton has other roles. It protects delicate organs such as the brain and heart. Its bones also make blood cells and store calcium, a mineral that is essential for healthy teeth.
There are also some differences in the male and female skeleton. The male skeleton is usually longer and has a high bone mass. The female skeleton, on the other hand, has a broader pelvis to accommodate for pregnancy and child birth.
Regardless of age or sex, the skeletal system can be broken down into two parts, known as the axial skeleton and the appendicular skeleton.
