The parathyroid hormone (PTH) is secreted by the parathyroid gland, four small glands located on the posterior surface of the thyroid gland. The hormone is regulated by the calcium and phosphate levels in the blood and acts primarily on the bone and kidneys to increase circulating levels of calcium.
Calcitonin, secreted by the thyroid gland inhibits osteoclasts and stimulates osteoblasts, thus decreasing blood calcium levels. Parathyroid hormone is secreted by the parathyroid glands, which are on the posterior side of the thyroid.
