The bone matrix is the structural framework of bones, composed mainly of organic and inorganic materials. The organic component primarily consists of collagen, a protein that provides flexibility and strength, while the inorganic part is mainly made up of hydroxyapatite, a mineral that gives bones their hardness. This combination allows bones to be both strong and resilient. In addition to collagen and hydroxyapatite, the bone matrix contains various proteins and minerals that contribute to bone health and function. Cells such as osteoblasts and osteocytes are embedded within the matrix, playing crucial roles in bone formation and maintenance. The bone matrix is essential for supporting the body's structure and facilitating movement.
