Body Facts: Skeletal System
- The largest bone is the pelvis, or hip bone. It actually consists of six bones joined firmly together.
- The longest bone is the femur in the thigh. It makes up almost one quarter of the body's total height.
- The smallest bone is the stirrup inside the ear. It is hardly larger than a grain of rice.
- The outer ears and the end of the nose do not have bones inside them. Their inner structure is supported by cartilage, which is lighter and more flexible than bone. This is why the nose and ears can be bent.
- After death, cartilage decomposes faster than bone. This is why the skulls of skeletons have no nose or ears.
