ANATOMY

Detailed explanation-1: -Calcium salts form the bulk of the inorganic material in bone. The function of calcium salts in bone is to provide it with strength and rigidity against compressive forces. Calcium salts are what makes bones hard and these are found in bone matrix as hydroxyapatite crystals.

Detailed explanation-2: -Extracellular matrix. The ECM of bone is a dynamic network composed of a vast variety of organic and inorganic constituents, including collagen, elastin, polysaccharides, and CaP nanocrystals.

Detailed explanation-3: -Inorganic Components:-They are mineral salts, mainly Hydroxyapatite (a cristallized form of tricalcium phosphate), some calcium carbonate, and small amount of magnesium hydroxide, fluoride and sulfate.

Detailed explanation-4: -Bone is a fascinating biomaterial composed mostly of type-I collagen fibers as an organic phase, apatite as an inorganic phase, and water molecules residing at the interfaces between these phases.
