Question

Calcitonin
A) Elevates potassium level in blood
B) Lowers calcium level in blood
C) Elevates calcium level in blood
D) No effect on calcium

Answer 1

Hint: Calcitonin production is also blocked by the hormone somatostatin, that can be released into the thyroid gland by C cells. Calcitonin is active in helping to control blood levels of phosphate and calcium, opposed to parathyroid hormone activity.

Complete answer:
First we should know about the Calcitonin to answer this question. Calcitonin is a hormone that the parafollicular cells (commonly referred to as C-cells) of the thyroid gland manufacturer in humans. This means that it serves to lower blood calcium levels. However, the significance of this function in humans remains uncertain, as there are no negative effects in patients that have extremely low or very high calcitonin levels.
Now, let us find the solution from the options-
- The function of osteoclasts, which are the cells needed to break down the bone, is impaired. The calcium in the bone is absorbed into the bloodstream as the bone breaks down. Thus option A is not the correct option.
- Raising the volume of bone calcium and reducing the levels of blood calcium are its key actions. The results of parathyroid hormone, which serves to increase calcium levels in the blood, are opposed to calcitonin.
- It may also reduce calcium reabsorption in the kidneys, contributing to reduced calcium levels in the blood. Thus option C is not the correct option.
- By inhibiting osteoclasts with calcitonin, the amount of calcium produced into the blood is directly decreased. This inhibition has, however, been demonstrated to be short-lived. Thus, option D is not the correct option.

Thus, the correct answer is option (B) Lowers Calcium level in blood.

Note:As a consequence of getting very little calcitonin, there does not seem to be any therapeutic impact on the body. There are no adverse effects or signs in people who have had their thyroid gland extracted and have unsafe levels of calcitonin in their blood.
