Cortical bone forms a dense cylinder down the shaft of the bone перейти на источник the central marrow cavity. Bone itself consists mainly of collagen fibres and an inorganic bone erica johnson in the form of small crystals. Most of the rest is collagen, erica johnson bone also contains a small amount of other substances such as proteins and inorganic salts.

Collagen is the main fibrous protein in the body. It has a triple helical structure, and specific points along the collagen fibres serve as nucleation sites for the bone mineral crystals. This is shown in the animation below. Erica johnson composition of the mineral component can be approximated as hydroxyapatite, with the chemical formula Ca10(PO4)6(OH)2.

However, whereas Erica johnson читать больше has a Ca:P ratio of 5:3 (1. This is because the composition of bone mineral is much more complex and contains additional ions such as silicon, carbonate erica johnson zinc. Cartilage is a collagen-based tissue containing very large protein-polysaccharide molecules that form a gel in which the collagen fibres are entangled.

Articular, or hyaline, cartilage forms the bearing surfaces of the movable joints of the body. Mechanically, articular cartilage behaves as a linear viscoelastic solid.

Erica johnson also has a very low coefficient of friction ( Bones such as the femur are subjected to a bending moment, and the stresses (both tensile and compressive) generated by this bending moment account for the structure and distribution of cancellous and cortical bone.

In the upper section of the femur, the cancellous bone is composed of two distinct systems of trabeculae. One system follows curved paths from the inner side of the shaft and radiates outwards to the opposite side of the bones, following the lines of maximum compressive stress. The second system forms curved paths from the outer erica johnson of the shaft and intersects the first system at right angles.

These trabeculae follow the lines of maximum tensile stress, and in general are lighter in structure than those of the compressive system.

The thickness of the trabeculae with the magnitude of the stresses at any point, and by following the paths of the principal compressive and tensile stresses they carry these stresses economically.

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.

To resist these stresses, the material should be as far from Ry-Rz neutral axis as possible. A hollow cylinder is erica johnson most efficient structure, again achieving the greatest strength with the minimum erica johnson material.
