Across
  1. 2. a break in a bone
  2. 5. the canal in the center of each osteon that contains minute blood vessels and nerve fibers that serve the needs of the osteocytes
  3. 8. elongated shaft of long bone
  4. 11. cartilage with abundant elastic fibers, more flexible than hyaline cartilage
  5. 12. fibrous membrane at the angle of cranial bones that accommodate brain growth in the fetus and infants
  6. 13. a layer of synovial membrane around a tendon
  7. 15. inflammation of the joints
  8. 16. a fibrous sac lined with synovial membrane and containing synovial fluid
  9. 17. fibrous that connects bones to bones
  10. 18. the bones of the limbs, including the bones of the pectoral and pelvic girdles
  11. 22. disease in children caused by vitamin D deficiency; distortion of legs
  12. 24. disease in which defective metabolism of uric and acid causes arthritis
  13. 25. the spherical or hemispherical head of one bone articulates with the cuplike socket of another
  14. 30. the rounded end of one bone of another. Moves around it own axis
  15. 31. the end of long bone, attached to the shaft
  16. 32. process involving bone formation and destruction in response to hormonal and mechanical factors
  17. 33. bone forming cells
  18. 34. increased softening of the bone resulting from a gradual decrease in the rate of bone formation
  19. 35. noncancellous portion of bone that consists largely of concentric lamellar osteons and interstitial lamellae
Down
  1. 1. the most compressible type of cartilage; resistant to stretch
  2. 3. inflammation in the joints
  3. 4. the articular surfaces are essentially flat, and they allow only short slipping or gliding movements
  4. 6. like condyloid joints, but they allow greater freedom of movement
  5. 7. the most abundant cartilage type in the body.
  6. 9. typically found within the cavities of spongy bone of long bones and in the dipole of flat bones
  7. 10. bones united by cartilage, no joint cavity is present
  8. 14. bones joined by fibrous tissue; no joint cavity is present
  9. 19. double-layered connective tissue that covers and nourishes the bone.
  10. 20. a cylindrical projection of bone fits into a rough shaped surface on another
  11. 21. mature bone cell
  12. 23. freely movable joints exhibiting a joint cavity; also called a diarthrosis
  13. 26. made up of skull, vertebral column, and body thorax.
  14. 27. the oval articular surface of one bone fits into a complementary depression in another
  15. 28. large cells that resorb or break down one matrix
  16. 29. internal layer of skeletal bone. Also called cancellous bone.
