Question

What effect does parathyroid hormones have on bones?

Answer 1

Parathyroid hormones have bones in them so they expand and open to bigger bones causing problems

Answer 2

Parathyroid hormone regulates serum calcium through its effects on bone, kidney, and the intestine: In bone, PTH enhances the release of calcium from the large reservoir contained in the bones. Bone resorption is the normal destruction of bone by osteoclasts, which are indirectly stimulated by PTH.
