Here are the essential concepts you must grasp in order to answer the question correctly.
Bone Matrix Composition
The bone matrix is a complex structure composed of both organic and inorganic components. The organic part primarily consists of collagen fibers, which provide tensile strength and flexibility, and various proteins that contribute to the overall structure. The inorganic component mainly includes hydroxyapatite, a mineral that gives bones their hardness and rigidity.

Organic Components
The organic components of bone matrix are primarily collagen, which makes up about 90% of the organic material, and non-collagenous proteins such as osteocalcin and osteopontin. These proteins play crucial roles in bone formation, mineralization, and the regulation of bone metabolism. The organic matrix is essential for maintaining the structural integrity and resilience of bones.

Inorganic Components
The inorganic components of the bone matrix are primarily composed of mineral salts, with hydroxyapatite being the most significant. This crystalline structure is formed from calcium and phosphate ions, providing bones with their strength and resistance to compression. The balance between organic and inorganic materials is vital for the overall mechanical properties of bone.
