The parathyroid glands are four pea-sized glands located on the thyroid gland in the neck . Occasionally, a person is born with one or more of the parathyroid glands embedded in the thyroid, the thymus, or elsewhere in the chest. In most such cases, however, the glands function normally.
Though their names are similar, the thyroid and parathyroid glands are entirely separate glands, each producing distinct hormones with specific functions. The parathyroid glands secrete parathyroid hormone (PTH), a substance that helps maintain the correct balance of calcium and phosphorous in the body. PTH regulates release of the calcium from bone, absorption of calcium in the intestine, and excretion of calcium in the urine.
When the amount of calcium in the blood falls too low, the parathyroid glands secrete just enough PTH to restore the balance. (Source: excerpt from Hyperparathyroidism: NIDDK)
Parathyroid gland: The parathyroid glands are an endocrine glands located in the anterior neck area on the lobes of the thyroid gland. There are four parathyroid glands, which produce parathyroid hormone, a natural antagonist to the action of the thyroid hormone calcitonin. The parathyroid glands work in opposition to calcitonin to help regulate calcium and phosphate in the body.
The parathyroid gland is made up of parathyroid chief cells. Conditions that can afflict the parathyroid glands include hyperparathyroidism, hypoparathyroidism, parathyroid adenoma, parathyroid tumors, and trauma.
