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.

The endocrine system is composed of glands that secrete hormones that regulate the activity of different body cells. The pituitary gland is often called the "master gland" because it controls the activities of other glands.
Discuss a disorder associated with either hypo or hypersecretion of a specific hormone secreted by the pituitary gland.
Include in your discussion the answer to the following:
What effect will an increase or decrease in production have on the target organs?What signs and symptoms are associated with this condition and how is it treated?

The underlying cause may differ. What symptoms would be associated with hyperthyroidism? 2) Autoimmune disease in which auto-antibodies stimulate the TSH receptor (TSHR) on the thyroid gland. How would this affect levels of TRH, TSH, and TH? Draw out the H-P-T axis to illustrate changes in each hormone. 3) What symptoms would be associated with hypothyroidism? 4) How could this disease be treated? When the thyroid cells are destroyed, they cannot make hormones anymore and TH replacement needs to be given.arrow_forwardDescribe the functions of the following hormones: TSH, thyroxine, calcitonin, PTH, ACTH, cortisol, insulin, glucagon, hGH, ADH, epinephrine, and aldosterone.arrow_forward
