- 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

- Can repair themselves when infected with bacteria and viruses
- Long shaft containing bone marrow, head covered with cartilage
