While covering Bones as part of my a-level we were told that
- 60% of bone is made up of inorganic material and this is good under compression
- 30% of bone is made up of organic components and this is good under tension
Does the composition vary depending of the function of the bone, e.g. does the femur have more inorganic component than a typical bone?
Thanks

Just a quick answer as i know you are itching to get this -
This is a paper which tackles the anatomical differences in bone composition :

These guys looked very carefully at the anatomical variation in various biochemical measures across the skeleton including hips (read femur) and vertebrae.

well not so coz genetically all the bones are made up of same composition some difference is in its reformation and on its use.
