The effects of microgravity on bone structure and function

WebBone formation occurs by osteoblasts secreting an organic matrix (osteoid) and then mineralizing the matrix. When the remodeling process is skewed such that, over time, there is more eating than replenishing, you get osteoporosis. When the remodeling process is aborted, say in avascular necrosis, bad bone accumulates. (Seen here as density). WebApr 18, 2013 · Bone is a dynamically remodeled tissue that requires gravity-mediated mechanical stimulation for maintenance of mineral content and structure. Homeostasis in bone occurs through a balance in the activities and signaling of osteoclasts, osteoblasts, and osteocytes, as well as proliferation and differentiation of their stem cell progenitors. … diamond lake exteriorsWebIn response to new stresses applied to a bone, remodeling increases bone strength by adding new bone tissue where appropriate.

The “activation” phase of remodeling is dependent on the effects of local and systemic factors on mesenchymal cells of the osteoblast lineage. These cells interact with hematopoietic precursors to form osteoclasts in the “resorption” phase.

WebOsteoporosis is the bone disorder, which decreases the bone mass, bone density, and makes the skeletal structure fragile. Factors that lead to osteoporosis include inhibition in the synthesis of osteoblasts, an increase in resorption of bone, lack of growth factors, and calcium deficiency. 4.
