Across 5. area where bone growth occurs 7. skeletal division with the skull and ribcage 10. fracture caused by twisting forces 14. the double-layered membrane on the external surface of the bone 15. openings in the periosteum that allow nerves and BV to travel through 16. this is store in bone and released in the bloodstream when needed 17. the structural unit of compact bone 20. this consists of proteoglycans and glcoproteins 22. they run through the core of every osteon 23. bones provide a place for muscles to attach and then act as these 24. main component of inorganic bone 26. space that holds the osteocyte 31. cells that maintain bones 36. sternum, ribs, skull, scapula 38. type of bone that resembles a honeycomb 39. when the bone fragments in 3 or more pieces 40. the end of long bones 41. disorder caused by the lack of calcium deposits, bones are soft and weak 42. bones that are cube shaped 43. each concentric tube in an osteon 44. cells that are mitotic stem cells 45. vertebrae, hip

Down 1. this hematopoietic tissue is found in spongy bones 2. tiny canals that connect the lacunae to each other 3. they run at right angles to the long axis of the bone and connect blood supply between periosteum and central canal 4. disorder caused when bone is deposited randomly and causes spotty weakness 6. the shaft of long bones 8. examples include depressions and projections 9. this process occurs in the marrow cavities 11. cartilage that surrounds the epiphyses of articulating bones 12. fracture in which the ends of bones are out of normal alignment 13. the center of the diaphysis 18. cells that destroy bone 19. bones are considered this level of organization 21. this is stored in the mineralized bone matrix 25. skeletal division with the girdles 27. cells that create bone 28. disorder when bone reabsorption occurs more than the deposition 29. plates of spongy bone 30. this chemical part of bone that contributes to its flexibility and tensile strength 32. fracture in which the bone is broken the entire way through 33. fracture that is at a right angle to the long axis 34. soft and weak bones in kids 35. type of anatomy that examines the surface of bones 37. layer of the periosteum that contains osteoblasts and osteoclasts
