Answer

Brief Explanations:

For Question 4, when plasma calcium concentration increases, the body's homeostatic response is the release of calcitonin from parafollicular C - cells of the thyroid gland to decrease calcium levels. PTH is released when calcium levels are low. For Question 5, thyroglobulin in the thyroid follicle is indeed a precursor and becomes part of T3 and T4 thyroid hormone molecules.

Answer:

Question 4: Calcitonin gets released from parafollicular c cells of the thyroid gland. Question 5: True
