In Graves' disease, the body attacks the thyroid gland tissue and causes it to overproduce thyroid hormones, resulting in elevated blood levels of T3 and T4.
Which of the following statements would be TRUE?
Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TRH and the Anterior Pituitary Gland would release more TSH.
Since blood levels of thyroid hormones are elevated, the hypothalamus would release more TRH and the Anterior Pituitary Gland would then stop releasing TSH.
Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TRH and the Anterior Pituitary Gland would not release TSH.
Since blood levels of thyroid hormones are elevated, the hypothalamus would not release TSH and the Anterior Pituitary Gland would not release TRH.
Which one of the following statements about T3 is FALSE?
1) It is thought to be the most active thyroid hormone.
2) It may be elevated to a greater extent than T4 in hyperthyroidism.
3) It is not bound to serum proteins.
4) It is commonly decreased in patients with nonthyroidal illness.

Which of the following statements best describes diseases of the thyroid gland?
Hyperthyroidism is associated with increased metabolism driven by increased sympathetic nervous drive.
Children with cretinism have elevated levels of thyroid hormones and catecholamine-induced tachycardia.
Hashimoto’s disease is more common in men than women and is associated with a goitre and unexplained weight gain.
