Bone is a highly specialized form of connective tissue that provides structural integrity and protection to the body's internal organs. Its composition is bipartite, consisting of a rigid, mineralized inorganic matrix, primarily calcium phosphate in the form of hydroxyapatite, embedded within a flexible organic framework largely composed of collagen. This structure allows bone to withstand significant mechanical stress while maintaining elasticity. Functionally, aside from providing a scaffold, bone serves as a critical reservoir for essential mineral ions, most notably calcium, which are regulated to maintain systemic homeostasis. Furthermore, bone tissue is metabolically active, undergoing a continuous process of remodeling—the coordinated breakdown of old material and the deposition of new matrix—which ensures structural maintenance and repair throughout life.
