Answer:
Inhibition of Calcitonin synthesis
Step-by-step explanation:
Calcitonin is secreted by the thyroid gland to regulate calcium and phosphorus levels in the blood. the Calcitonin slows down the osteoclasts activity which in-turn decreases blood calcium. A decrease in calcium serum levels stimulates the parathyroid hormones which inhibits the synthesis of Calcitonin and regulates the calcium serum levels.
