3 Skeletal Activites Flashcards
How do bones grow by width
Appositional growth
What happens in the hyaline cartilage model
Interstitial and Appositional cartilage growth causes lengthening and widening
What happens during primary ossification center formation
Osteoblasts produce bone trabeculae in diaphysis
Blood vessels invade cartilage
What happens during medullary cavity development
Mature bone produced from woven bone by remodeling
What parts of bone are still cartilage after formation
Epiphyseal growth plate
Articular cartilage
What hormones influence bone development
Estrogen and androgen
How does the osteogenic layer of the periosteum grow
Appositional growth
Where does bone formation occur during bone growth
Periosteal surface
Where does bone resorption occur during bone growth
Endocortical surface
Where does bone remodeling occur by osteoclasts and blasts relative to each other
Same surface
What are the 5 ways a fracture is classified
Etiology Displacement Relation to external environment Pattern Location
What is direct bone healing
No callus
Osteonal remodeling
What is indirect bone healing
When fixation and stabilization are inadequate for primary
