Three theories were dominant: from 1949 to 1970 the connective tissue origin was popular, which stated that osteoclasts and osteoblasts are of the same lineage, and osteoblasts fuse together to form osteoclasts. After years of controversy it is now clear that these cells develop from the self fusion of macrophages. It was in the beginning of 1980 that the monocyte phagocytic system wa…

WebMar 17, 2024 · Thyroid-stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3) stimulate osteoblastic activity and cause bone elongation at the epiphyseal plate of long bones through chondrocyte proliferation. In states of hypothyroidism or hyperthyroidism, the degree of bone turnover is low and high, respectively. WebParathyroid hormone (PTH) acts on osteoblasts to promote their activity and survival. PTH also has an indirect effect on osteoclasts through its role in calcium homeostasis. High levels of calcium increase endogenous PTH production, which then acts on bone to stimulate further absorption of calcium into the blood.
