Function of the parathyroid glands. Parathyroid glands produce parathyroid hormone, which plays a key role in the regulation of calcium levels in the blood. Precise calcium levels are important in the human body, since small changes can cause muscle and nerve problems.
What is the function of the parathyroid glands? Your parathyroid glands have one job: making and releasing parathyroid hormone (PTH). Together, PTH and another hormone — calcitonin — tightly control the levels of calcium in your bloodstream.
Parathyroid hormone (PTH) is a hormone your parathyroid glands release to control calcium levels in your blood. It also controls phosphorus and vitamin D levels. If your body has too much or too little parathyroid hormone, it can cause symptoms related to abnormal blood calcium levels.
The parathyroid glands secrete parathyroid hormone (PTH), which regulates calcium levels in the blood and tissues through its effects on bones, the kidneys, and the intestine. PTH raises the level of calcium in the blood when the level of calcium is too low (a condition called hypocalcemia).
Hyperparathyroidism is when your parathyroid glands create high amounts of parathyroid hormone in the bloodstream. These glands, located behind the thyroid at the bottom of your neck, are about the size of a grain of rice.
The major function of the parathyroid glands is to maintain the body's calcium and phosphate levels within a very narrow range, so that the nervous and muscular systems can function properly. The parathyroid glands do this by secreting parathyroid hormone (PTH).
The parathyroid glands are four small circular glandular structures embedded in the posterior surface of the thyroid gland. They are an endocrine gland, producing parathyroid hormone (parathormone, PTH) which acts to control the level of calcium and phosphorus in the blood.
The parathyroid glands (light pink) produce parathyroid hormone, which increases levels of calcium in the blood. The parathyroid glands are small pea-sized glands located in the neck just behind the butterfly-shaped thyroid gland. Most people have four parathyroid glands, with two parathyroid glands lying behind each 'wing' of the thyroid gland.
Parathyroid Gland Function. The parathyroid gland’s main role is in secreting parathyroid hormone (PTH). PTH acts by raising the levels of calcium in the blood. This is accomplished by PTH’s ability to do three things. First, PTH can stimulate the breakdown of bone, which inherently releases calcium from the stores held within the bone.
There are typically 4 parathyroid glands. As the name implies, they are located near the thyroid gland in the neck, although the number and particularly the location are quite variable. These pea-sized glands play a vital role in maintaining the body's calcium level. (See also Hypercalcemia and Hypocalcemia.)
