    Calcium salts give the bone its hard texture and are shaped around the collagen fibres. What are collagen fibres? The collagen fibre allows the bones to bend under strain and stops the risk of the bones fracturing due to them being brittle. Bones are able to withstand weight; the bones protect tissues such as the heart, lungs and brain, as they are the weaker tissues. Some bones contain bone marrow whereas others the bones marrow produces blood cells that are vital for the body The bones cells are called osteocytes, these cells are located in the matrix on rings which are known as lamellae, the rings system is called osteone or a haversain system. It is in the osteone where the blood vessels and nerves pass through the hollow centre. The responsibilities of the bones is to allow tendons to attach themselves to them, provide support…

    is similar, although keloids grow beyond wound margins. KELOIDS Keloids represent a pathological response to cutaneous injury resulting in disfiguring scars with no known satisfactory treatment (Figure 1). Skin injuries such as burns, inflammation, surgery or minor trauma,insect bite induce an overabundant ECM deposition, especially collagen41. Even the spontaneous development of keloids has been discussed 42 but may be the result of a minor, overlooked trauma. Pathophysiology of keloid A…

  • Dentin Adhesion Essay

    INTRODUCTION : The concept of dentin adhesion presently used involves the nanomechanical retention which is due to polymerisation of hydrophilic monomers around acid exposed collagen fibres.1 The entanglement of these monomers within the exposed collagen fibres gives rise to the so called Hybrid layer , which is also referred as Resin infiltrated Dentin layer.2 The presence of hybrid layer is important for attainment of a leakage free interface between the cavity walls and resin composite.2…

    While the structure of the collagen is normal, there is less collagen than there should be. There is little or no bone deformity, bones fracture easily, most often occurs before puberty. The effects of osteogenesis imperfecta may extend to the teeth, making them prone to cavities and cracking. The whites of the eyes may have a blue, purple, or gray tint.

  • Carbohydrate Benefits

    Carbohydrate and fat are the other macro nutrients that provide calories. They play important roles in wound healing. Carbohydrates break down into glucose, the major fuel for collagen synthesis. Carbohydrate will still make up 50-60% of the diet. This is important since glucose is the body’s main source of energy for healing and for cell repair and for proper brain function. Some fat is also essential in every diet. Typically, the recommend amount of total fat is 30%. Unsaturated fat such as…

    that break by even the slightest touch. According to an article, osteogenesis imperfecta “rare genetic disorder that in the large majority of cases is caused by mutations in genes that code for collagen type I” Brittle bones disease is a relatively rare disease affecting close to 1 in every 30,000 live births or 1 in every 60,000 live births for OI Type II. There are 4 different genes that produce the collagen needed for healthy bone development. These genes, if defective, can cause 8 variations…
