Detailed explanation-1: -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.

Detailed explanation-2: -Parathyroid hormone is secreted from four parathyroid glands, which are small glands in the neck, located behind the thyroid gland. Parathyroid hormone regulates calcium levels in the blood, largely by increasing the levels when they are too low.

Detailed explanation-3: -The parathyroid glands are small endocrine glands situated just below the thyroid glands in the neck. They are usually four in number, two behind each thyroid gland. They are very small, pea-sized and weigh about 50 mg. The glands function to maintain the calcium and phosphorus levels in our bodies.

Detailed explanation-4: -Parathyroid hormone regulates calcium levels in your blood by affecting the following parts of your body: Bones: Parathyroid hormone stimulates the release of small amounts of calcium from your bones into your bloodstream.

Detailed explanation-5: -PTH metabolism. PTH is a single-chain hormone of 84 amino acids that is mainly produced by chief cells of the parathyroid glands. PTH is cleaved from pre-pro–PTH and thereafter stored in secretory granules awaiting 1 of 2 fates: circadian and pulsatile secretion or intracellular degradation.
