Skeletal System
Across
- 3. extends from the scapula to the elbow
- 4. the portion of the skeleton that consists of the skull, hyoid bone, vertebral column, and thoracic cage
- 5. cartilage,
- 11. form bone tissue within the membranous layers
- 12. forms the lowest part of the vertebral canal
- 14. extends from the hip to the knee
- 15. occurs in the yolk sack, liver and spleen, and red bone marrow
- 16. joints connected by a layer of cartilage
- 18. a cavity in the diaphysis
- 19. articulates with the humerus, ulna, and wrists
- 20. break down bone matrix
- 22. a plate that remains between the primary and secondary ossification centers
- 23. articulates with the radius laterally and with a disc of fibrocartilage
- 25. located on the medial side of the leg
- 26. ends of bones that form joints with adjacent bones
- 28. amount of carpal bones in the wrist
- 29. consists of a manubrium, bod, and xiphoid processes
- 30. fills the medullary cavity
- 31. triangular structure formed of five fused vertebrae
- 32. bones that develop as hyaline cartilage that is later replaced by bone tissue
Down
- 1. round
- 2. joints tightly joined by a layer of dense connective tissue
- 4. the portion of the skeleton that includes the pectoral girdle and upper limbs
- 6. twelve pairs attached to twelve thoracic vertebrae.
- 7. broad, triangular bones that articulate with the humerus of each upper limb
- 8. second vertebra
- 9. bone with continuous extracellular matrix
- 10. mature bone cells
- 12. rodlike bones located between the sternum and scapulae
- 13. located on the later side of the tibia
- 17. bone with irregular interconnecting spaces between bony plates
- 21. encloses and protects the brain
- 24. first vertebra
- 27. a joint covered with hyaline cartilage
