Best Answer

The parathyroid glands (4 of them) secrete parathyroid hormone to increase blood calcium. When the parathyroid glands detect low blood calcium levels, they secrete more parathyroid hormone, which causes the bones to release calcium to the bloodstream, thereby increasing blood calcium levels.

The hormone produced by the para follicular cells of the thyroid

gland is calcitonin (CT).

CT can decrease the level of calcium in the blood by inhibiting

the action of osteoclasts, the cells that break down bone extracellular

matrix. The secretion of CT is controlled by a negative

feedback system.

When its blood level is high,calcitonin lowers the amount of

blood calcium and phosphates by inhibiting bone resorption

(breakdown of bone extracellular matrix) by osteoclasts and by

accelerating uptake of calcium and phosphates into bone extracellular

matrix.

What hormone stimulates the release of calcium?

the parathyroid hormone (PTH) is released by the parathyroid gland (located behind the thyroid gland). A decrease in blood calcium causes the parathyroid gland to secrete PTH which causes the bones to release more calcium to raise blood calcium and also causes the kidneys to decrease the amount of calcium lost in urine
