Question 3) 62. Which is not true about bone remodeling?
A. It occurs throughout life.
B. It assists in the maintenance of calcium and phosphate levels in the body.
C. It occurs at both the endosteal and periosteal surfaces of the bone.
D. It occurs only at articular surfaces.
E. It can occur in response to stress on a bone.

Question 4) Mechanical stress of bones, such as that caused by weight lifting, is detected by
A. osteocytes, which then communicate to osteoblasts to increase synthesis of osteoid.
B. osteoclasts, which then communicate to osteocytes to increase the size of lacunae.
C. chondrocytes, which then trigger osteoblasts to increase bone in a lengthwise fashion.
D. osteoblasts, which then communicate to osteocytes and osteoclasts to deposit more hydroxyapatite.

(
Question 6) Which is an accurate description of appositional bone growth?
A. Osteoblasts build bone at the circumferential lamellae while osteoclasts widen the medullary cavity.
B. Osteoclasts build bone at the concentric lamellae while osteoblasts build bone at the interstitial lamellae.
C. Osteoblasts build bone at the concentric lamellae while osteoclasts build bone at the epiphyses.
D. Osteocytes build bone at the interstitial lamellae while osteoclasts expand the length of the medullary cavity.
E. Osteocytes and osteoclasts expand the bone at its epiphyses, chondrocytes construct cartilage.
