Document Summary
In this situation, the bone has been dried with all water removed. Made up of organic and inorganic matter. Define organic + inorganic matter: organic: c containing compounds, inorganic: minerals. 33% organic tissue: fibrous tissues + cells: organic matrix of bone made up of collagen, protein and polysaccharide ground substance (type of ct found between cells & collagen fibers) called gags (glycoaminoglycans) (glycoprotein) which contains chondroitin sulfate. Chondrotin sulfate (a sulfated gags) provides resistance to compression in day to day activities. Role of organic tissue in bone: resilience, toughness, and flexibility. Resilience = referred to durability on a day to day basis and ability to return to its original form no matter how it is handles. Next slide: tremendous amount of ca in bone. 10 cc bone contains 10 g ca (1 cc = 1 ml in volume) Most tissues: 6 mg or 0. 006 g/ 10 cc.
