  • Skeletons
    • Internal skeleton advantages-flexible,allows easy attachment of muscles
    • Dangerous to move people with bone injuries-broken vertebrae can damage the spinal cord, causing paralysis or death
    • Cartilage and bone are living tissues
      • Long shaft containing bone marrow, head covered with cartilage
        • Hollow, lighter and stronger
      • Can repair themselves when infected with bacteria and viruses
    • Human skeleton is first made of cartilage-the cartilage is slowly replaced with bone
      • If cartilage remains between the head and the shaft, the person is still growing
    • The bones of elderly people lack calcium and phosphorus
