Question

Parathormone causes
A. Increased level of serum calcium
B. Increased level of blood sugar
C. Decreased level of serum calcium
D. Decreased level of blood sugar

Answer 1

Parathormone is also known as parathyrin, parathyroid hormone, and PTH. Parathormone is a substance produced by the parathyroid gland and helps the body to store and use calcium. A higher or lower amount than its normal level of parathormone causes various health disorders.

Complete answer:
The parathyroid hormone is released by four parathyroid glands, which are small glands present in the neck, just behind the thyroid gland. It is alternatively known as parathyroid hormone, parathyrin, and PTH. Parathormone mainly functions as a regulator of calcium levels in the blood, by increasing the levels of calcium in the blood is too low. This function is done by the hormone through its actions on the kidneys, bones, and intestine
The calcium levels in the blood are mainly regulated by parathyroid hormone through the negative feedback of the parathyroid glands. When the calcium levels in the blood get down than normal level parathyroid hormone stimulates its secretion and in contrast, calcium levels in the blood become higher than the normal level the release of parathyroid hormone is blocked.
A primary problem is that when the parathyroid hormone produces too much in the parathyroid glands, it causes rise in the calcium levels in the blood and this condition is known as hypercalcemia and this condition is referred to as primary hyperparathyroidism. Thus, parathormone or parathyroid hormone causes an increase in the level of serum calcium
When a little amount of parathyroid hormone or parathormone is produced by the parathyroid glands, it causes low levels of calcium in the blood. This condition is known as hypocalcaemia. Though it is a rare medical condition. This condition is usually treated medically with oral calcium and vitamin D.
The condition of the body that arises due to increase in the blood sugar levels is known as hyperglycaemia or high blood sugar and is due to improper functioning of hormone insulin. It is commonly known as diabetes and can cause damage in the nervous system, blood system and other internal organs such as kidneys etc. In certain conditions, the blood sugar falls or is decreased than the normal level and the condition is known as hypoglycaemia.

Therefore, the correct option is option A.

Note: Parathormone is a hormone that is generated by the human parathyroid glands which are mainly responsible for the maintenance of calcium and phosphorus balance. The excessive release of parathormone causes an increase in calcium levels in the blood while the deficiency of parathormone causes decrease in calcium levels in the blood.
