A 68-yeаr-оld pоstmenоpаusаl woman with a history of low physical activity falls from standing height and fractures her hip. Using skeletal structure, bone physiology, and joint concepts, answer each part fully. (a) Explain, in terms of osteoblast and osteoclast activity, why this patient's bone density most likely declined after menopause, and how that change raised her fracture risk. (b) Bone matrix contains both collagen and hydroxyapatite. Explain how EACH contributes to bone's mechanical behavior, and explain why a loss of bone mass increases fracture risk under otherwise normal loads. (c) The hip is a ball-and-socket synovial joint. Identify TWO structures of a synovial joint and explain how each contributes to the trade-off between mobility and stability. Then predict ONE consequence that would follow if the articular cartilage of this joint degenerated over time.
