Detailed explanation-1: -Bones become more brittle and may break more easily. Overall height decreases, mainly because the trunk and spine shorten. Breakdown of the joints may lead to inflammation, pain, stiffness, and deformity. Joint changes affect almost all older people. These changes range from minor stiffness to severe arthritis.
Detailed explanation-2: -What is osteomalacia? Osteomalacia is the name of a condition where bones become soft and weak. This means they can bend and break more easily than normal. The most common cause is not having enough vitamin D.
Detailed explanation-3: -The process of bone formation is called osteogenesis or ossification. After progenitor cells form osteoblastic lines, they proceed with three stages of development of cell differentiation, called proliferation, maturation of matrix, and mineralization.
Detailed explanation-4: -Summary. Bone contains several growth factors, including bone morphogenetic proteins (BMPs), transforming growth factor beta (TGF-), insulin-like growth factors I and II (IGF-I and IGF-II), platelet derived growth factor (PDGF) and basic and acidic fibroblast growth factor (bFGF and aFGF).
