2. The skeleton The skeleton forms the framework of the human body It has five main functions: –Support — it gives the body a structure (to which muscles attach) –Protection — it protects the vital organs (eg the brain) from injury –Movement — it enables movement where two bones come together at the joints –Shape — it makes the body tall, short, broad or narrow –Contains bone marrow — which produces blood cells and stores mineral salts

3. How bones grow The skeletal system of an embryo starts off as cartilage — a firm but elastic material As the embryo grows, cartilage gradually changes to bone — this is called ossification This process continues throughout childhood Ossification replaces and repairs bones throughout life
