NEET PG DENTAL EXAM

Detailed explanation-1: -This hormone raises calcium levels by releasing calcium from your bones, increasing the amount of calcium absorbed from your small intestine and decreasing the amount of calcium lost in urine. When blood-calcium levels are too high, the parathyroid glands produce less parathyroid hormone.

Detailed explanation-2: -It causes resortion/demineralisation of the bone which results in movement of calcium from bones to blood. It also stimulates the reabsorption of calcium ions by the renal tubules and increases the calcium absorption from the digested food.

Detailed explanation-3: -Although the parathyroid glands are intimately related to the thyroid gland anatomically, they have no related function. The thyroid gland regulates the body’s metabolism and has no effect on calcium levels while parathyroid glands regulate calcium levels and have no effect on metabolism.
