GENERAL HISTOLOGY

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: -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 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-4: -Also called parathormone, parathyrin, and PTH.
