A healthy human body has four glands just below the thyroid called as parathyroid glands. These glands are noway related with the functioning of thyroid gland but acts as a thermal regulator that controls the levels of calcium in the blood. The calcium sensing receptors attached to the parathyroid gland helps in maintaining the calcium levels in the blood. Low blood condition, primary hyperparathyroidism, secondary hyperparathyroidism are the common parathyroid conditions.
