x :)))))
risk factors of osteoporosis:
drugs + smoking
- e.g. cortisone, alcohol ⇒ decreases osteoblast acitivity
- smoking - decreases estrogen

drugs
Bone Repair process:
- begins with _______ of a ____ _____
- clot ______ by a ______ - consists of ______ ______ + fibrocartilage islets
- callus ______ ⇒ intramembranous + endochondral ________
- takes _ - _ weeks ⇒ cast _______ since movement can ________ new matrix
- begins with formation of a blood clot
- clot replaced by a callus - consists of fibrous network + fibrocartilage islets
- callus ossifies ⇒ intramembranous + endochondral ossification
- takes 4 - 6 weeks ⇒ cast required since movement can refracture new matrix
- _______ ____ formation of a blood clot
- ____ replaced by a callus - _______ of fibrous network + ___________ ______
- _______ ossifies ⇒_________ + _________ ossification
- takes 4 - 6 weeks ⇒ ______ required since ________ can refracture _____ _______
