1bone formation by the activity of osteoblasts, osteoclasts, and addition of minerals and salts
ossification
2what are the two forms of ossification
intramembranous and endochondral
3formation of bone direct from mesencymal cells
intramembranous ossification
4formation of bone within hyaline cartilage (most of the post cranial skeleton)
endochondral ossification
5what is the process of endochondral classification
1. osteoblasts create bony collar
2. blood vessels invade, bringing in more osteoblasts
3. similar process for epiphyses
4. cartilaginous growth plate maintained during longitudinal growth
5. eventually bone cells out pace cartilage cells and epiphyses fuse
6growth in diamete of bone
appositional growth
7what are the three phases of fracture healing
reactive phase
reparative phase
remodeling phase
8what happens during the reactive phase
- fracture and inflammation
- granulation tissue formation
9what happens during the reparative phase
cartilage callus formation
lamellar bone deposition
10what happens during the remodeling phase
remodeling to original bone contour
11another way to look at the fracture healing process
1. hematoma formation
2. fibrocartilage callus formation
3. bony callus formation
4. bone remodeling
