Select the most accurate answer 10. Which of the following is NOT correct? A. Bone fracture is partial or complete break in the contimuity of the bone B. Bone remodelling, continuing process of synthesis and destruction that gives bone its mature structure and maintains normal calcium levels in the body C. bone resorption the process by which osteoclasts break down the tissue in bones and release the minerals D. Osteoblasts release hydrochloric acid and acidic proteases such as cathepsin K. resulting in degradation of the bone matrix and liberation of Ca, PO,, and fragments of type I collagen E. osteoblasts have receptors for PTH and, when activated, produce osteoclast stimulating factor (cytokine) 11. Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating cytoplasmic processes of the junctions for communication extent into these canals and are joined together by gap  A. osteogenic cell B. osteoblast C. osteocyte D. osteoclast E. chondrocyte 12.…

Kindly choose the correct answer. One answer per question only. MODULE 17 Question 1A main role of proteoglycans in bone is to: A. actively mineralize the bone B. aid collagen polymerization C. attract water that acts to cushion compression D. stabilize tendon attachments Question 2 Select one answer. For the following, identify the macroscopic structures of compact bone: Compact bone A. lamellae B. osteons C. trabeculae  D. hydroxyapatite

Match the definitions with the correct term. osteoblast A. The layer that lines medullary cavity of a long bone B. epiphyseal fracture Stem cells for bone tissue that differentiates into other types of bone cells C. osteogenic cell In the structure of compact bone, circular layers of bone matrix that forms the D. periosteum osteons. concentric lamellae The process where bone tissues are continuously recycled and renewed with organic and mineral components of the bone matrix throughout life E. bone remodeling F. Which fracture can affect a child's growth in height if not treated carefully? endosteum G. H. greenstick fracture

16. Osteons I are the fundamental functional unit of much spongy bone II are aligned parallel to the long axis of the bone III. are cylindrical structures that contain a mineral matrix (lamellae) and living cells connected by canaliculi IV. they suround a canal containing blood vessels, nerves, and loose connective tissue (Haversian system) A.
