";s:4:"text";s:4124:"These salt crystals form when calcium phosphate and calcium carbonate combine to create hydroxyapatite, which incorporates other inorganic salts like magnesium hydroxide, fluoride, and sulfate as it crystallizes, or calcifies, on the collagen fibers. Learn. To resist these stresses, the material should be as far from the neutral axis as possible. Raeghan_Rudkin.
Bone Cells Composition of bones (continued) Flashcards. Sagittal section through long bone showing the internal structure of the bone. Mechanically, articular cartilage behaves as a linear viscoelastic solid. Composition of Bone.
This section will examine the gross anatomy of bone first and then move on to its histology.The osteocytes are located inside spaces called lacunae (singular = lacuna), found at the borders of adjacent lamellae. Composition of bone ~1/3 organic ◦ Collagen fiber matrix (~88%) organized around lamellae ◦ Non-collagen (~12%); Glycoproteins, proteoglycans, lipids, etc) ~1/3 inorganic (mineral) ◦ Mostly dense calcium phosphate in the form of highly insoluble crystals of hydroxyapatite ~1/3 water Cells – osteoblasts, osteoclasts, osteocytes, bone lining cells Re-productivity of content are not allowed. As described earlier, canaliculi connect with the canaliculi of other lacunae and eventually with the central canal.
Bone is anisotropic: material properties are different in different directions.
These trabeculae follow the lines of maximum tensile stress, and in general are lighter in structure than those of the compressive system.Cortical bone forms a dense cylinder down the shaft of the bone surrounding the central marrow cavity. The greatest strength is therefore achieved with the minimum of material.The distribution of the compact bone in the shaft is also due to the requirement to resist the bending moment stresses. It’s a great marketing tool that allows you to share your presentations with marketers, presenters, educationists and others anywhere around the world, and lightning fast. It can be found under the periosteum and in the diaphyses of long bones, where it provides support and protection.
