Detailed explanation-1: -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.

Detailed explanation-2: -The parathyroid glands lie behind the thyroid. They produce parathyroid hormone, which plays a role in regulating the body’s blood level of calcium and phosphorus. Hyperparathyroidism is when your parathyroid glands create high amounts of parathyroid hormone in the bloodstream.

Detailed explanation-3: -The parathyroid glands in the throat make parathyroid hormone, which regulates the amounts of calcium, phosphorus and magnesium in the bones and blood. Problems include overactivity (hyperparathyroidism) and underactivity (hypoparathyroidism).

Detailed explanation-4: -The parathyroid glands’ function is to maintain serum calcium homeostasis through synthesis and release of PTH. At the bone, PTH inhibits osteoblast activity and stimulates osteoclast activity leading to bone breakdown and calcium release.
