What are growth hormone, thyroid hormone and sex hormones Growth in diameter (thickness) of long bones What is appositional growth The breakdown of bone is accomplished by What are osteoclasts DOUBLE JEOPARDY Two regulators of bone remodeling What is the hormone feedback loop (calcitonin and PTH) and responses to mechanical forces (Wolff’s Law) Classification of a fracture based on the orientation of the break What is linear or transverse Mineralization of bone generally refers to Calcification, in which calcium crystals are packed together forming the hard compact bone Bone remodeling occurs here Where is the periosteal and endosteal surfaces Bone resorption and bone deposit together are referred to as What is bone remodeling This disorder literally means “soft bones” What is osteomalacia This disorder can cause bowing of the legs in young children What is rickets Osteoporosis can be treated with hormone replacement therapy because What is estrogen promotes bone growth Smoking is a risk factor for osteoporosis because. What is smoking decreases estrogen levels The long axis of a bone What is the diaphysis DOUBLE JEOPARDY The membrane that covers compact bone What is the periostem The structural unit of compact bone What is the osteon The concentric circles that make up an osteon What are lamella The channels that connect one lacunae to another What are canaliculi Bone cells What are osteocytes Realignment of bones in which the physician coaxes the bones into place What is closed reduction Acids secreted in resorption bays act to What is convert calcium crystals into soluble calcium that can diffuse into the blood A disorder in which bone resorption outpaces bone deposit leading to weak and brittle bones What is osteoporosis Calcification occurs at this zone of the epiphyseal plate. What is the osteogenic zone
