Does collagen in bone resist tension?
Collagen is the main component that resist tension. Elastic fibers also resist tension but behaves similar to rubber in that it can be stretched and will recoil after the force is removed. On the other side are glycosaminoglycans that resist compressive forces.
What is the role of collagen in the bones?
Collagen is the most abundant protein in the human body, found in the bones, muscles, skin, and tendons. Collagen forms a scaffold that provides strength and structure within the body. It is an essential component of connective tissue and plays a crucial role in holding the body's cells together.
What type of fibers or minerals do you find in the extracellular matrix of bone How does this composition relate to the properties of bone?
How does this composition relate to the properties of bone? Mainly, collagen fibers are found in the extracellular matrix of bone. This deals with the composition because collagen is a very strong and sturdy material,, allowing the bones to be very stable. 4.
What type of fibers or minerals do you find in the extracellular matrix of bone?
Collagen is the most common protein in the human body and is found frequently in extracellular bone tissue, making up about 30% of the bone. Collagen fibre is like cement, or a framework to stick things together.
What properties does collagen give to bone?
Type I collagen makes up 90 % of the organic matrix. Mineral plays a major role in determining bone stiffness and yield strength, whereas post-yield properties such as ultimate strength and toughness are believed to be dependent on an intact collagen network [3, 4].
What is the role of collagen in bones quizlet?
Collagen is found in the connective tissues of the body and makes up a large portion of the bones and cartilage. It holds tissues together, providing strength and mass to the bones.
How do bones withstand tension and compression?
Bone is resistant to bending, twisting, compression and stretch. It is hard, because it is calcified, and the collagen fibres help the bone to resist tensile stresses. If you dissolve away the calcium salts of bone, then the bone becomes rubbery because of the collagen fibres which are left behind.
How would denaturing collagen from the bone matrix affect the physical properties of a bone?
How would denaturing collagen from the bone matrix affect the physical properties of a bone? The bone would be more brittle.
What material contributes the most to the compressive strength of bone?
Answer and Explanation: Calcium carbonate and calcium phosphate contribute the greatest to the compressive strength of bone.
What provides strength and rigidity to the bone matrix?
Bone matrix The hardness and rigidity of bone is due to the presence of mineral salt in the osteoid matrix, which is a crystalline complex of calcium and phosphate (hydroxyapatite).
Why is compact bone resistant to breakage?
Finally, compact bone is covered by a double-layered membrane called a periosteum. The inner layer of the periosteum contains osteoblasts, which are cells that secrete collagen as well as mineral salts, which increase bone's resistance to breakage.
Is collagen a fiber?
Collagen fiber is the fiber in the extracellular matrix of connective tissues characterized by being elongated and made up of collagen glycoproteins. It is typically arranged in branching bundles of indefinite length. It is a strong insoluble fiber. It occurs in the skin, tendon, ligaments, bone, and cartilage.

What is the process of maturation of collagen?
Different processes of maturation of collagen occur in bone, which can result either from enzymatic or nonenzymatic processes. The enzymatic process involves activation of lysyl oxidase, which leads to the formation of immature and mature crosslinks that stabilize the collagen fibrils.
What are the determinants of bone quality?
Different determinants of bone quality are interrelated, especially the mineral and collagen, and analysis of their specific roles in bone strength is difficult. This review describes the interactions of type I collagen with the mineral and the contribution of the orientations of the collagen fibers when the bone is submitted to mechanical forces.
What is the function of bone?
Bone is a complex tissue of which the principal function is to resist mechanical forces and fractures. Bone strength depends not only on the quantity of bone tissue but also on the quality, which is characterized by the geometry and the shape of bones, the microarchitecture of the trabecular bones, the turnover, the mineral, and the collagen.
Does collagen affect bone strength?
These modifications of collagen are age-related and may impair the mechanical properties of bone. To illustrate the role of the crosslinking process of collagen in bone strength, clinical disorders associated with bone collagen abnormalities and bone fragility, such as osteogenesis imperfecta and osteoporosis, are described.
What mineral gives bones their strength?
Enter calcium, the mineral that gives bone its strength and hardness. When bone develops, calcium crystals form in the gaps and bond to the flexible collagen like mortar amid the bricks.
What is bone tissue made of?
“Nature has no reason for making a bone round or square. The outlines of bones, therefore, follow the stress lines or are vertical to them so that they give an indication of the pressures the bone has to withstand. But this ideal distribution of bone material along the stress lines would have been to little avail were the material itself not so well adapted to extraordinary pressure. Just like fiberglass made of synthetics threaded with glass fiber, bone tissue is made up of two constituents which greatly differ in their mechanical properties. About half the bone volume is made up of inorganic crystalline material. It consists of phosphate, calcium, and hydroxyl ions and comes very close to hydroxylapatite in structure. It appears in the bone in the form of tiny crystals, only about 200 atomic diameters in size. They are inserted between thin fiber hairs of the elastic material collagen and seem to be linked with them. Many of these parallel inorganic and organic building blocks form fascicles, which may be interwoven in various ways. The end product is a material that is considerably stiffer than collagen, though low in weight, but by far not as brittle and inelastic as pure hydroxylapatite. Besides, because of the continuous alternation between brittle and elastic material, there is little chance for a fracture to spread unchecked.” (Tributsch 1984:32-33)
