Document Summary
What is bone (dry matter basis): dry matter basis where all water has been removed from the bone. Examining bone composition without any water present: made up of organic and inorganic matter. Inorganic minerals, ash: 33% organic tissue fibrous tissues + cells. Resilience is the durability of bone and its ability to return to its original form no matter how it is handled: 67% inorganic salts dry matter basis. Function of minerals and inorganic salts: hardness, rigidity, give resistance to x-rays, bone structure would be affected if salts were removed. Process of decalcification would be done with acid. Removing calcium eliminates the rigidity of bone so it becomes flexible and we can tie into a knot: bone structure would be affected if organic tissue were removed. Organic tissue removed by burning off carbon containing compounds. Composition of bone when water is still present: mostly water, 25% or more than what most people think that bone would contain.
