    1. Which of these lists the six categories for classifying bone by shape? Intramembranous; periosteal; diaphysis mesenchymal; endochondral; interstitial Flat; irregular; short; long; sesamoid; sutural Long; short; mesenchymal; intramembranous; endochondral; epiphyseal Femur; sternum; wormian; pelvis; patella; vertebra Answer: 2Answer: 2

    2. Which bony marking is correctly paired with its description? Fissure; depression Facet; opening Tuberosity; process formed where tendons or ligaments attach Spine; process formed for articulation with adjacent bones Answer: 3Answer: 3

    3. Which of these bony markings would become more pronounced with weight-bearing exercise? Tuberosities Condyles Processes Heads Answer: 1Answer: 1

    4. Which of the following describes osteoprogenitor cells? Divide to produce daughter cells that differentiate into osteoblasts Assist in elevating local concentrations of calcium phosphate Multinucleate and derive from same stem cells that produce monocytes Maintain protein and mineral content of surrounding matrix Answer: 1Answer: 1

    5. Answer: 4Answer: 4

    6. Answer: 4Answer: 4

    7. What are functional relationships between compact and spongy bone? Spongy bone resists stress from many directions/compact bone is extremely strong when stressed along the axis of alignment Spongy bone is strong along its main axis/compact bone resists stress from many directions Both spongy and compact bone resist stresses from all angles except a sudden force to the side of the bone None of these is correct Answer: 1Answer: 1

    8. Answer: 4Answer: 4

    9. Answer: 4Answer: 4

    10. Answer: 4Answer: 4

    11. Answer: 3Answer: 3

    12. Answer: 1Answer: 1

    13. How is bone remodeling accomplished? Osteoblasts form new bone matrix. Osteocytes remove and replace calcium salts. Osteoclasts are not active, thus producing stronger bone. 1 and 2. Answer: 4Answer: 4

    14. Why were some people sickened by radioactivity years after the Chernobyl accident? Osteoclasts do not differentiate between heavy metals and calcium Turnover of bone matrix caused release of stored radiation into circulation Osteoblasts are a type of memory cell and recall the poisons that enter them Heavy metal ions are stored in the bloodstream Answer: 2Answer: 2

    15. Answer: 2Answer: 2

    16. Answer: 4Answer: 4

    17. Answer: 1Answer: 1

    18. Which hormone is correctly paired with its function? Calcitonin/stimulates osteoclast activity PTH/reduces calcium ion concentration of body fluids Calcitrol/inhibits calcium and phosphate ion absorption along the digestive tract Thyroxine/stimulates osteoblast activity Answer: 4Answer: 4

    19. Answer: 3Answer: 3

    20. Answer: 1Answer: 1

    21. Answer: 4Answer: 4

    22. Answer: 1Answer: 1

    23. A balance between which two hormones is essential for maintaining calcium homeostasis? Calcitrol and parathyroid hormone Calcitrol and thyroxine Calcitonin and parathyroid hormone Growth hormone and sex hormones Answer: 3Answer: 3

    24. Why are women usually shorter than men at maturity? Estrogens cause faster epiphyseal plate closure. Androgens cause faster epiphyseal plate closure. Thyroxine increases the rate of osteoblast activity in boys before puberty. Men have more growth hormone. Answer: 1Answer: 1

    25. Why would you expect that all people lose some height as they age? Osteomalacia causes the bones to soften. Osteopenia causes a reduction in bone mass. Osteoporosis causes a reduction in bone mass. Growth hormone is no longer available. Answer: 2Answer: 2

    26. Answer: 3Answer: 3
