Does PTH Inhibit Osteoblast Activity? In contrast, when secreted continuously at relatively high doses (as seen in patients with pHPT), PTH stimulates osteoclast-mediated bone resorption and suppresses osteoblast activity. Does PTH stimulate osteoblasts? An increase in osteoblast differentiation rather than osteoblast proliferation appears to be the main mechanism by which PTH stimulates osteoblastogenesis. Indeed, PTH
Does The Skeletal System Release Hormones? Our bones secrete a protein called osteocalcin, discovered in the 1970s, that rebuilds the skeleton. In 2007, Karsenty and colleagues discovered that this protein acts as a hormone to keep blood sugar levels in check and burn fat. Does the skeletal system excrete hormones? Both rodents and humans release
How Are Ballerinas Bones Affected During Space Travel? Astronauts experience spaceflight osteopenia when they are in space. This condition can cause astronauts to lose bone mass in their legs, hips, and spines . Once the astronauts return to Earth, it can take three or four years for those bones to recover! How does space travel
