MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Parathyroid hormone regulates calcium levels in the blood, largely by increasing the levels when they are too low. It does this through its actions on the kidneys, bones and intestine: Bones – parathyroid hormone stimulates the release of calcium from large calcium stores in the bones into the bloodstream.

Detailed explanation-3: -Calcium levels are regulated by the parathyroid glands. That’s all the parathyroid glands do! Through the secretion of parathyroid hormone (PTH), these four small glands regulate how much calcium is absorbed from our diet, how much calcium is secreted by our kidneys, and how much calcium is stored in our bones.
