Did you know that bones are constantly mineralizing and demineralizing in your body? Your bones not only hold up your body, but they also act like a storage bank for minerals.
Bones are Malleable
Bone tissue is a type of dense connective tissue that under goes constant remodeling. The body will only maintain bone and muscle cells where they are needed in order to conserve energy. This means that if a bone goes unused, the body will start to take away bone cells! Whether your body chooses to tear down or build up your bone, is up to what nutrients you eat and how you move....but MOSTLY it is up to how you move and the frequency of the demands you put on its structure. All this translates into: Your bones are shaped by how you use your body, and you can change to some degree (within your genetic potential), the shape of your bones slowly over time. Remember they are tissue- just like your muscles, fascia and the rest of your living body!
"External force guides the regrowth of bone tissue in a healthy person". This theory even extends to fractures that heal imperfectly! The idea is that as the vectors of pressure are applied to the fractured bone (assumed after initial healing process the bone is used normally again), it will continue to build up and break down the "unused" areas that previously healed imperfectly, until the bone has been remodeled into a more perfect design for usability. This may explain how long ago, before casts, people could have the chance to walk again after a broken leg. People of long ago probably rested only until they could start walking on their broken leg again- probably much earlier than now a days. This may have caused a crooked heal site. But over time- going off of Wolff's Law, the bones may have continued to remodel back to a more effective shape to walk on- so eventually the crooked heal site becomes straight! Wow!
We Have "Nano Crystals" in our Bones
Bone is mostly made up of collagen, but also hydroxyapatite, calcium, phosphate and other salts. The strands of collagen give bone its tensile strength, and the interspersed crystals of hydroxyapatite give bone its compressional strength. Scientists have always been amazed at how flexible yet strong bones are. Microscopically, there is a pattern of collagen and hydroxy- Apatite crystals that form a type of lattice. It is this amazing lattice of collagen and crystal that give us flexible but hard bones!
Bones have electric potential
Human bones are piezoelectric. (Many crystals are also piezoelectric). This means that when it is compressed and released, charges are created. This is the real science behind how Wolff's Law works. Where there is a negative current from a bone being bent a certain way- the cells tend to build up there- and vice versa. Just think: every time you jump, you are sending a small electric charge through your bones! The force travels in lines or vectors that reverberate through your body.
Did you know Apatite crystals are found in the earth? Some people think that wearing Apatite jewelry helps strengthen bones and teeth. Afterall- our bodies do use that mineral in making the material to form bones and teeth!!
