GENERAL HISTOLOGY

Detailed explanation-1: -Parathyroid hormone (PTH) is a hormone that your parathyroid glands make and release to control the level of calcium in your blood by increasing it. PTH also helps control the levels of phosphorus (a mineral) and vitamin D (a hormone) in your blood and bones.

Detailed explanation-2: -Calcium homeostasis is maintained by actions of hormones that regulate calcium transport in the gut, kidneys, and bone. The 3 primary hormones are parathyroid hormone (PTH) 1, 25-dihydroxyvitamin D-3 (Vitamin D3), and calcitonin.

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: -Parathyroid hormone (PTH) levels are mainly controlled by a feedback loop of calcium levels in your blood to your parathyroid glands. In other words, low calcium levels in your blood stimulate parathyroid hormone release, whereas high calcium levels in your blood prevent your glands from releasing parathyroid hormone.

Detailed explanation-5: -Also called parathormone, parathyrin, and PTH.
