Which of the following is NOT a parathyroid gland mechanism to maintain adequate levels of blood calcium?
A) inhibition of calcitonin synthesis
B) activation of osteoclasts
C) increased intestinal absorption of calcium ions
D) increased calcium ion reabsorption by the kidneys

Question

Quizplus · Accepted Answer

The parathyroid gland does not inhibit calcitonin synthesis. Calcitonin is produced by the thyroid gland and acts to reduce blood calcium levels, whereas the parathyroid gland secretes parathyroid hormone (PTH) to increase blood calcium levels. The other mechanisms listed (activation of osteoclasts, increased intestinal absorption of calcium ions, and increased calcium ion reabsorption by the kidneys) are all mechanisms by which the parathyroid gland maintains adequate levels of blood calcium.
