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