and develop into osteoblasts
describe the function of osteoblasts - CORRECT ANSWER-cell reproduction for forming new bone
describe the function of osteocytes - CORRECT ANSWER-reshapes bones, primary cell in mature
bone

Describe the three phases of hair growth - CORRECT ANSWER-1) Anagen phase- (longest part) active
phase of growth where living cells of the hair bulb are rapidly growing, dividing, and transforming
into hair
2) Catagen phase- (short phase) brief regression period where cell division ceases and the follicle
undergoes involution
3) Telogen phase- (resting phase) hair is shed, 3-4 months hair starts regrowing and enters the
anagen phase
Describe the different types of bone. - CORRECT ANSWER-Simple fracture, compound fracture,
stress fracture, and pathologic fracture

overlying
, What is a stress fracture? - CORRECT ANSWER-thin break, caused by increased physical activity
which bone experiences repetitive loads
What is a pathologic fracture? - CORRECT ANSWER-Occurs when bone has been weakened by
disease
What hormones cause bone growth to stop? - CORRECT ANSWER-Glucocorticoids (high amounts
increase bone loss, impair growth at the epiphyseal plate
