What is the primary effect of intermittent low doses of Parathyroid Hormone (PTH) on osteoblasts?
Show answer and explanation
Correct answer: It stimulates osteoblast activity and bone formation.
While chronic high levels of PTH promote bone resorption, intermittent low doses actually have an anabolic effect. They stimulate osteoblast survival and activity, which is a mechanism used in some treatments for osteoporosis.
