Question
Diagram the control of thyroid hormone secretion.
Step 1

Draw a labelled diagram of the pituitary gland and Describe the hormones secreted by Neurohypophysis.
The diagram shows the normal feedback loop that controls the production of thyroid hormones in the human body. Graves’ disease is an autoimmune disease in which the body produces autoantibodies to the TSH receptor. When these autoantibodies bind to the receptor, it mimics the action of the TSH hormone. How would the feedback loop and the regulated production of thyroid hormones shown in the diagram be affected in a person with Graves’ disease? a. The feedback loop would be disrupted. Autoantibodies would bind to the TSH receptors, allowing them to continue to produce thyroid hormones. As a result, there would be an overproduction of thyroid hormones because the negative feedback system would be unable to function. b. The feedback loop would be not be disrupted. Autoantibodies would bind to the TSH receptors, allowing them to continue to produce thyroid hormones. As a result, there would be an overproduction of thyroid hormones because the negative feedback system would be unable to function. c. The feedback loop would be disrupted. Autoantibodies would not bind to the TSH receptors, allowing them to continue to produce thyroid hormones. As a result, there would be an overproduction of thyroid hormones because the negative feedback system would be unable to function. d. The feedback loop would be disrupted. Autoantibodies would bind to the TSH receptors, allowing them to continue to produce thyroid hormones. As a result, there would be an overproduction of thyroid hormones because the negative feedback system was functional.
