Bones are living organs what are they made up of? The compact bone that makes up the outer surface of bone is called? What are that make up approximately what percentage of bone? Name organic protein is responsible for the bone matrix that hydroxyapatite binds to? When does bone growth and modeling start? The two-step process in which bone tissue is recycled is called? Define the Bone cells and which one that are responsible for eroding the bone surface during? In addition to proper growth and development, bone remodeling is critical in maintaining? By about what age does generally begin to occur more rapidly than bone formation? Name factors are associated with a lower peak bone density? Currently the most accurate assessment tool for measuring bone density is? What does T-score signify?
1) The type of bone growth in which bones form directly from mesenchyme is called a) intramembranous ossification b) appositional ossification c) interstitial ossification 2) Which of these is not a step in intramembranous ossification? a) compact bone replaces woven bone b) osteoid calcifies c) woven bone forms d) a bony collar forms around the bone 3) Which of the following statements about woven bone is false? a) It is characteristic of the development of embryonic flat bones. b) It contains no trabeculae. c) It is the same as spongy bone of adults. 4) Which of the following is true regarding endochondral ossification? a) Bone begins replacing the cartilage model shortly after birth. b) The majority of the bones of the body are formed in this way. c) The epiphysis gets its blood supply from the diaphyseal periosteal bud. d) The marrow cavity is the first bony structure to form. 5) Which of the following is true regarding bone remodeling? a) If osteoblasts are more active than osteoclasts, more bone will be resorbed than formed. b) Bone remodeling occurs at the same rate in all bones of the body. c) Bone remodeling can occur to help us maintain adequate concentrations of calcium and phosphate in our blood. d) Osteoblasts function to break down bone. 6) In osteoporosis, bone resorption occurs at a faster rate than the deposition of new bone. Using your knowledge of bone cells, you reason that the cause of this must be an increase in activity and number of a) Osteocytes b) Osteoclasts c) Osteoprogenitor cells d) Osteoblasts
