A.
"Stimulating-hormone functions are not disrupted by thyroid disorders."
B.
"The pituitary gland keeps secreting TSH to try to make the thyroid function."
C.
"TSH exists in an inverse relationship with the other thyroid hormones."
D.
"Thyroid hormone function is very poorly understood and the reason is not clear.
ANS: B
Because the levels of thyroid hormone are low, the anterior pituitary gland keeps secreting more and more TSH to try to force the thyroid into producing its hormones. This also clues the provider that the problem is in the thyroid gland itself, not in the brain regulating system. The other answers are not accurate.
