WebBone resorption is the process by which osteoclasts break down the bone tissue. This process is critical in the maintenance of blood calcium levels. Abnormal increases in the activity of osteoclasts that produce an increase in bone resorption cause osteoporosis and other bone loss-associated diseases. WebHighly increased bone resorption in cancellous bone leads to general bone loss and destruction of local architecture because of penetrative resorption and microfractures. In cortical bone the first response of estrogen withdrawal is enhanced endocortical resorption. Later, also intracortical porosity increases. things to talk about in school
