- 13. What does PTH stand for?
- 14. Calcium cannot be absorbed from the small intestine without ____
- 15. Plays a role in the structure of bone
- 17. Stimulates osteoclast proliferation and activity
- 18. Inhibits osteoclast activity and stimulates calcium uptake by the bones, thus reducing the concentration of calcium ions in the blood
- 19. Green leafy ____ are a good source of vitamin K
Down
- 1. Is a disease characterized by a decrease in bone mass that occurs when the rate of bone resorption exceeds the rate of bone formation
- 2. Supports bone mineralization and may have a synergistic role with vitamin D
- 3. This system produces and secretes hormones, controlling bone growth, maintaining bone once it is formed, and remodeling it
- 4. This loss of bone mass is thought to be caused by the lack of this stress
- 5. Enters spaces within hydroxyapatite crystals, thus increasing their density
- 7. Is a critical component of bones
- 9. can interfere with the function of osteoblasts
- 11. A hormone secreted by the thyroid gland promotes osteoblastic activity and the synthesis of bone matrix
- 12. This gland controls bone growth which includes increasing the length of long bones, increasing calcium retention, which enhances mineralization, and stimulating osteoblastic activity
- 16. This disease makes new bone formed in an attempt to keep up with the resorption by the overactive osteoclasts
- 20. People who exercise regularly have ___ bones
