During the third month after conception, the perichondrium that surrounds the hyaline cartilage "models" becomes infiltrated with blood vessels and osteoblasts and changes into a periosteum primary ossification occurs at the _______________ diaphysis secondary ossification occurs at the _________________ epiphysis What are the only two secondary centers that show ossification at birth? 1. distal femoral 2. proximal tibial Are primary or secondary ossification centers present at birth? primary EXCEPT: - distal femur - proximal tibia primary ossification = @ ___________ secondary ossification = @ _________ primary @ diaphysis secondary @ epiphysis Where does long bone growth occur? epiphyseal plate traction epiphysis located where tendons attach to bones and are subjected to a pulling, or traction, force Wolff's Law A bone grows or remodels in response to forces or demands placed upon it - "bone grows in response to mechanical stress" ↑ stress = _______ Ca2+ ↑ stress = ↑ Ca2+ in bones What are the main things that allows bones to grow? - moderate mechanical stress - adequate mineralization What leads to stress fractures in bones? TOO much excessive bone stress - repeated loading is much higher than ability to repair bone disuse = _____ bone mineralization = ↓ bone mineralization ***its important to use our bones/move our bodies to ensure proper bone mineralization & remodeling - moderate stress = GOOD open fracture a fracture in which there is an open wound or break in the skin near the site of the broken bone closed fracture bone is broken, but the skin is intact comminuted fracture fracture in which the
