25. Osteoclasts 10 Ossification and Remodeling

26. 20. What are immature bone cells that produce new matrix are called? *Known as bone forming cells

27. Osteoblasts 20 Ossification and Remodeling

28. 30 ? What are the mature bone cells that maintain normal bone structure by recycling the calcium salts in the bony matrix around themselves.? Ossification and Remodeling

30. 40 Replacing cartilage with bone is known as? Ossification and Remodeling

31. 40 *(Endochondral) ossification

32. 50 Place the stages of Endochondral Ossification in the correct order: 1. Blood vessels invade the inner cartilage and new osteoblasts form spongy bone at a primary ossification center 2. Chondrocytes enlarge and calcify. 3. Secondary ossification centers form in the epiphyses. 4. Osteoclasts begin to break down spongy bone in center, creating a marrow.. 5. Bone forms at the shaft (diaphysis) surface. Ossification and Remodeling

34. 10 Fractures and Parts of the Skeleton What is a compound fracture?

35. 10 Fractures and Parts of the Skeleton results in bone projecting through the skin.

36. 20 Fractures and Parts of the Skeleton What could someone do to help strengthen their bones to prevent fractures?

37. 20 Fractures and Parts of the Skeleton *Increase calcium ingestion -raises blood calcium levels and triggers osteoblasts to form new bone. This new formation of bone can help diminish bone decrease due to overactive osteoclasts, making bones stronger*exercise * *ultimately will prevent osteoporosis (a decrease in the calcium content of bones which leads to bones that are weak and brittle)

57. 50 Potpourri What is the difference between compact bone and spongy bone?

58. 50 Potpourri * Compact bone has osteons situated in closely packed areas and is found where stresses come from a limited range of direction. Compact bone provides strength. *Spongy bone has large spaces between thin, bony plates and is found where stresses are few or come from many different directions. Spongy bone serves to reduce the weight of bones.
