Webb19 sep. 2024 · The organic fraction of the bone matrix is mainly collagen, one of the most abundant proteins in the human body. Collagen is a multimeric fibrous protein, whose structure is similar to a rope or rope, since it is composed of several subunits or fibrils. WebbBone matrix is composed mainly of inorganic materials, while the bone organic compartment is a minor and complex structural entity, surrounding and supporting cells. …

The skeleton is a large organ that is formed and degraded throughout life in the air-breathing vertebrates. The skeleton, often referred to as the skeletal system, is important both as a supporting structure and for maintenance of calcium, phosphate, and acid-base status in the whole organism. The functional part of bone, the bone matrix, is entirely extracellular. The bone matrix consists of protein and mineral. The protein forms the organic matrix. It is synthesized and then t…

WebbBone matrix consists of collagen fibers and organic ground substance, primarily hydroxyapatite formed from calcium salts. Osteogenic cells develop into osteoblasts. Osteoblasts are cells that make new bone. They become osteocytes, the cells of mature bone, when they get trapped in the matrix.
