Question

Parathyroid hormone (PTH) is responsible for regulating calcium levels in the blood by stimulating osteoclast activity to breakdown bone tissue and release calcium. If the osteoclasts are overactive, it suggests that PTH levels are elevated and causing excessive bone resorption. This could lead to multiple bone breaks and other bone-related issues. Natriuretic peptide is a hormone involved in regulating salt and water balance, thyroxine is involved in metabolism regulation, and calcitonin has the opposite effect of PTH and inhibits osteoclast activity. None of these hormones are directly related to overactive osteoclasts and bone breaks.
