Question

Quizplus · Accepted Answer

Osteoporosis is characterized by reduced bone mass due to diminished laying down of the organic matrix of bone, leading to bone fragility and increased risk of fractures. Abnormal bone calcification and hypocalcemia are not defining features of osteoporosis. In fact, osteoporosis can lead to the opposite, hypercalcemia, due to increased bone resorption. Osteoblast hyperactivity is not characteristic of osteoporosis; in fact, it is osteoclast hyperactivity (which breaks down bone tissue) that is responsible for the reduction in bone mass seen in osteoporosis.
