which statements characterize bone remodeling

Bone may also be resorbed for remodeling, if the applied stresses have changed. After this phase, the bones keep on changing every day, so as to adapt to functional demands imposed by human activity. ... All of the following characterize a periodontal cyst except one. Woven bone fills the entire defect and remodeling starts along the periphery (C). Increases in bone remodeling with teriparatide have been shown to be associated with reduced levels of trabecular microdamage, even in patients with prior bisphosphonate treatment and damage accumulation. 1 – 4 The bone marrow is highly vascularized; its vessels act as gates for hematopoietic niches and the blood to exchange information, cells, nutrients, and waste products. The eight cranial bones are the frontal bone, two parietal bones, two temporal bones, occipital bone, sphenoid bone, and the ethmoid bone. Remodeling of bone is a continuous process that occurs throughout life. Bone growth and bone formation are differently regulated in children and adults under different disease conditions. ... All of the following statements about periodontal disease are true EXCEPT: Women are more likely to have severe bone loss than men. Methods that provide quantitative … By the WoundSource Editors The stages of wound healing proceed in an organized way and follow four processes: hemostasis, inflammation, proliferation and maturation. lular matrix elaboration events that characterize the establishment of the interface between newly formed bone and solid surfaces. For this reason, bone replacement biomaterials such as demineralized freeze-dried bone allografts and xenografts have been recently used for sinus augmentation with good clinical results and various authors recently reported on the resorption and remodeling of the materials [5,6]. Which one is the exception? Insert the letter in the answer blanks. The defect initially fills with connective tissue (A). Using the key choices, characterize the following statements relating to long bones. Like bone, enamel is a nanocomposite of bioapatite and 161 organic components, but enamel differs from bone in multiple ways: it is > 95 wt% mineral 162 (apatite), with the remainder as water and proteins other than collagen; its crystallites are about 163 10 times larger in width and thickness than in bone, but 1000+ times longer. Acrylic bone cements (ABCs) have played a key role in orthopedic surgery mainly in arthroplasties, but their use is increasingly extending to other applications, such as remodeling of cancerous bones, cranioplasties, and vertebroplasties. Osseous Tissue: Bone Matrix and Cells Bone Matrix Osseous tissue is a connective tissue and like all connective tissues contains relatively few cells and large amounts of extracellular matrix. Wnt activity is antagonized by endogenous proteins including dickkopf-1 (DKK-1). Which of the following statements may explain how mechanical forces talk to cells responsible for bone remodeling? As a result, bone abnormalities are found almost universally ... new and had not been applied to characterize populations in published clinical studies. Although the bones developed separately in the embryo and fetus, in the adult, they are tightly fused with connective tissue and adjoining bones do not move (Figure 19.6). We prove the conical dierentiability of the solution to a bone remodeling contact rod model, for given data (applied loads and rigid obstacle), with respect to small perturbations of the cross section of the rod. Try to make some general statements about the structure of equilibrium as a function of the parameters. These solid sur- faces either may be implant materials, or indeed previously formed bone matrix, which has been resorbed during normal bone remodeling events. During degradation and remodeling starts along the periphery ( C ) a promising tool to characterize populations published.
