How does gravity affect bone remodeling
WebBone remodeling is a necessary process to repair damaged bone and involves the resorption and formation of hard tissue. OCs, OBs, and osteocytes are the cells maintaining bone matrix homeostasis in bone. Immune cells, especially macrophages, are critical in the bone-remodeling process in response to damage and other inflammatory stimuli ... WebIn response to new stresses applied to a bone, remodeling increases bone strength by adding new bone tissue where appropriate. Remodeling enables calcium stored in the …

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). WebSpace flight is a new experience for humans. Humans adapt if not perfectly, rather well to life without gravity. There is a reductive remodeling of the musculo-skeletal system. Protein is lost from muscles and calcium from bones with anti-gravity functions. The observed biochemical and physiological changes reflect this accommodative process.
