Osteoporosis and Bone Diseases Quiz

Which of the following statements accurately describes primary osteoporosis and its contributing factors?

• Primary osteoporosis is primarily caused by excessive calcium intake and affects only young adults.

• Primary osteoporosis is a common condition that typically arises after menopause in women and can also develop in older men due to factors such as decreased estrogen levels.

• Primary osteoporosis is a rare condition that only occurs in individuals with a family history of bone diseases.

• Primary osteoporosis is characterized by increased bone density and is unrelated to hormonal changes.

How does menopause affect a woman's risk of developing osteoporosis?

• It increases the production of estrogen, leading to accelerated bone loss.

• Age and genetics

• Medications

• Increase IL-1, IL-6 and TNF a

Which of the following best describes the primary difference between osteomalacia and osteoporosis?

• Osteomalacia is caused by excessive calcium intake, while osteoporosis is due to vitamin D deficiency.

• Osteomalacia results in soft bones due to inadequate mineralization, whereas osteoporosis leads to decreased bone density and increased fracture risk.

• Osteomalacia primarily affects older adults, while osteoporosis is more common in children.

• Osteomalacia is a genetic disorder, while osteoporosis is primarily an acquired condition

What is Rickets?

• A disease in children caused by vitamin D deficiency causing a lack of calcification and, therefore, soft bones

• A disease caused by poor collagen synthesis, defective matrix formation, and increased bone reabsorption

• A condition characterized by abnormally high levels of calcium

• When bone becomes very porous and brittle, which can lead to fractures

What is Paget's Disease?

• A disease that disrupts the replacement of old bone tissue with new bone tissue

• A disease that disrupts the replacement of new bone tissue with new old tissue

• A disease that disrupts cancellous bone

• A disease that disrupts trabecular bone

Which metabolic bone disease is characterized by a loss of mineralized bone mass, causing increased porosity of the skeleton and susceptibility to fractures?

• Osteomalacia

• Osteopenia

• Osteoporosis

• Osteitis deformans

Which cellular component is most prominent in brown tumors on histology?

• Plasma cells

• Chondrocytes

• Multinucleated osteoclast-like giant cells

• Adipocytes

Which feature is common to both osteitis fibrosa cystica and brown tumors?

• Osteoid production

• Fibrous marrow replacement

• Cartilage cap

• Woven bone formation

In osteitis fibrosa cystica, the primary bone pathology is due to:

• Vitamin D deficiency

• Hypervitaminosis D

• Excess PTH stimulating osteoclastic bone resorption

• Failure of osteoid mineralization

What gives the 'brown' color to brown tumors?

• Hemosiderin deposition from hemorrhage

• Lipid accumulation in osteocytes

• Increased collagen content

• Calcified matrix
