If you are struggling with symptoms of a thyroid disorder and suspect thyroxine deficiency, it's crucial that you talk with an endocrinologist. The overall effect of calcitonin is to lower the concentration of calcium in the blood when it rises above the normal value. C) thymosin.

Slowing down or speeding up your heart rate. A) FSH. B) is responsible for milk expression from the mammary glands. B) erythropoietin In the intestines, parathyroid hormone helps with vitamin D metabolism. However, since bone resorption and bone formation are coupled processes, eventually calcitonin's inhibition of osteoclastic activity leads to increased osteoblastic activity (as an indirect effect).

[19] Dr. Copp named the discovered hormone calcitonin because of its role in 'maintaining normal calcium tone'.[18]. The action of calcitonin is therefore to cause a reduction in serum calcium, an effect opposite to that of parathyroid hormone. C) oxytocin.
