What is the term for thinning of the bones caused by the reabsorption of calcium into the bones?

• A. Osteoporosis
• B. Osteoarthritis
• C. Osteomalacia
• D. Rickets

Answer: (A)

The concept being tested is bone density loss from imbalanced bone remodeling. In osteoporosis, bone resorption outpaces bone formation, so calcium and mineral content leave the bone and it becomes thinner and more porous. This weakened bone structure leads to a higher risk of fractures, especially in the spine, hip, and wrist. Osteoarthritis involves wear-and-tear changes at joints rather than a systemic drop in bone density. Osteomalacia and rickets are due to defective mineralization from vitamin D deficiency, causing soft bones and deformities rather than simply thinning from increased resorption.
