[{'content': 'The tensile strength of the wound starts and increase after – \nSelect and explain. \nA. Immediate suture of the wound, B. 3 to 4 days, C. 6 months, D. 7 to 10 days', 'role': 'user'}, {'content': 'Answer: D \nExplanation: The strands of collagen give bone its tensile strength, and the interspersed crystals of hydroxyapatite give\xa0bone its compressional strength. These effects are synergistic.\nBone components are:-\n\nInorganic elements (65%)\nOrganic matrix (35%)\n\nInorganic elements :\n\nIt is the mineral phase, principally composed of calcium and phosphate, mostly in\xa0the form of hydroxyapatite .\n\nOrganic matrix :\n\nOrganic matrix consists of cells of bones and protein of matrix. This unmineralized matrix is called\xa0osteoid, i.e. unmineralized bone is known as osteoid. Osteoid with mineral (i.e. mineralized osteoid) is\xa0complete bone.\n\na. Protein of matrix:\n\nIt is mainly formed by type I collagen and a family of noncollagenous proteins like\xa0osteocalcin and osteonectin that are derived mainly from osteoblasts.\n\nb. Cells of the matrix:\nThe cells of bone are\n\nOsteoblasts\nOsteoclasts\nOsteocytes', 'role': 'assistant'}]
