Across
- 3. a tough sheath of dense irregular connective tissue & its associated blood vessels that surrounds the bone surface wherever it is not covered by articular cartilage
- 7. the addition of minerals and collagen fibers to bone by osteoblasts
- 9. contains the bones of the upper and lower limbs, or appendages, that connect the limbs to the axial skeleton
- 12. cells that digest protein and mineral components of bone extracellular matrix (resorption) which is part of the normal development, growth, maintenance, and repair of bone
- 16. the distal and proximal ends of the bone
- 18. "soft spots" that are found between cranial bones at birth
- 19. have complex shapes and cannot be grouped into any other bone categories
- 20. a hollow, cylindrical space within the diaphysis that contains fatty yellow bone marrow in adults -- also known as the marrow cavity
- 22. mature bone cells that are the main cells in bone tissue and maintain its daily metabolism
- 25. contains few spaces and is arranged in repeating structural units called osteons
- 28. a thin layer of hyaline cartilage covering the part of the epiphysis where the bone forms an articulation (joint) with another bone
- 29. loss of bone minerals
Down
- 1. process of producing red blood cells, white blood cells, & platelets
- 2. an immovable joint, which in most cases in an adult holds the skull bones together
- 4. somewhat cube-shaped and nearly equal in length and width
- 5. generally thin, provide considerable protection, & provide extensive surfaces for muscle attachment
- 6. the removal of minerals and collagen fibers from bone by osteoclasts
- 8. unspecialized stem cells that are the only bone cells to undergo cell division
- 10. bone-building cells
- 11. does not contain osteons; is composed of irregular latticeworks of thin columns of bone
- 13. consists of the bones that lie around the longitudinal axis of the human body
- 14. produces red blood cells, white blood cells, & platelets
- 15. the process by which bone forms
- 16. a thin membrane that lines the medullary cavity
- 17. the bone's shaft or body -- the long, cylindrical, main portion of the bone
- 20. regions in a mature bone where the diaphysis joins the epiphysis
- 21. consists mainly of adipose cells, which store triglycerides
- 23. the site of the growth plate; once bone growth in length stops, the epiphyseal line is the bony structure that replaces the cartilage that was once present
- 24. the process by which bone tissue hardens
- 26. have greater length than width and consist of a shaft and variable number of ends
- 27. any break in a bone
