The Skeletal System

4. required for bone hardness
5. joint which cannot move, fibrous tissue joins the bone
8. lining of the marrow cavity which contains osteoblasts and osteoclasts
10. synthesized by skin and required for absorption of calcium in the intesting
13. marrow located in epiphysis of long bones where hematopoiesis occurs
14. cells responsible for producing new connective tissue
15. slightly moveable joint, cartilage joins bone
17. "soft spots" where the skull hasn't fused together
21. cells responsible for resorption or breaking down of bone tissue
23. shaft of long bone
25. bone tissue is removed by osteoclasts and osteoblasts
26. landmark required to administer injection into deltoid muscle
27. landmark required to administer injection in vastus lateralis or ventrogluteal muscles
28. foot moves down at the ankle, toes point down

1. movement which occurs away from body midline
2. membrane covering the bone comprised of dense irregular connective tissue
3. tip of sternum made of cartilage, landmark for CPR
6. comprised of 26 bones in the adult
7. movement when the palm faces up
9. ends of long bone, irregular in shape, where growth plates are located
11. freely moveable joints, most common in human body, also known as synovial joints as they contain synovial fluid for lubrication
12. movement when the palm faces down
16. foot moves up at the ankle, toes point up
18. cells responsible for building bone tissue
19. movement which occurs toward body midline
20. opening in base of skull where spinal cord attaches to the brain
22. location on sternum overlying where trachea splits
24. cells responsible for producing new hyaline cartilage
