Ossification and Remodeling
5050
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.

2020 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 *exercise
**ultimately will prevent osteoporosis (a decrease in the calcium content of bones which leads to bones that are weak and brittle)

What is the difference between compact bone and spongy bone?What is the difference between compact bone and spongy bone?
5050 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.
