The blood calcium level is lowered by the deficiency of:
1 Both calcitonin and parathormone
2 Calcitonin
3 Parathormone
4 Thyroxine
Explanation:
Parathormone is a peptide hormone secreted by the parathyroid glands. It is a hypercalcemic hormone. It increases the calcium level in blood by promoting demineralization of bones, reabsorption of calcium from the renal tubules and absorption in the intestine. Thus, deficiency of parathormone (PTH) leads to the lower blood calcium level.

Hormone parathormone or parathyroid hormone, secreted by parathyroid gland, is responsible for
1 Regulate absorption and reabsorption of calcium by intestine and in kidney
2 Regulate quantity of calcium and phosphate ion in blood
3 regulate absorption (by intestine) reabsorption in kidney and quantity of \(\mathrm{Ca} 2+\) in blood
4 All of the above statement are correct regarding parathormone
Explanation:
Exp. D Parathormone or parathyroid hormone is a secretion of parathyroid gland. The secretion of this gland regulate absorption and responsible of calcium ion by intestine and in kidney quantity of phosphate and calcium in blood.

The hormone that increase blood calcium levels by promoting absorption of \(\mathrm{Ca}^{2+}\) from gastro intestinal tract.
1 Thyroxin
2 Calcitonin
3 Calcitriol
4 Catecholamines
Explanation:
The hormone that increase blood calcium levels by promoting absorption of \(\mathrm{Ca}^{2+}\) from the gastro intestinal tract is calcitriol. Calcitriol is the active form of vitamin D. It is produced in the kidneys and help to increase the absorption of calcium from the intestines.

1 Sella turcica is a bony cavity in which pituitary gland is located
2 Parathyroid hormone decreases the \(\mathrm{Ca}^{+2}\) levels in blood
3 Thymosin plays a major role in T-cell differentiation
4 The middle zone of adrenal cortex is zona fasiculata
Explanation:
Parathyroid hormone increases the \(\mathrm{Ca}^{2+}\) levels in blood. \(\mathrm{Ca}^{2+}\) is the abbreviation for calcium ion concentration in blood. Parathroid hormone regulate the calcium levels in the blood by stimulating the breakdown of bone to release calcium into the blood.
