1. If the pituitary fails to produce TSH, what will happen to thyroid hormone and TRH secretion?

2. Would the above be considered a prmary or secondary, hypothyroidism or hyperthyroidism?

3. An individual with a low metaboli rate improves with the administration of thyroid hormones, but shows no improvement upon injection of TSH. This person's low metabolic rate originates at what gland?(Give the rationale behind your conclusion)

4. WHy must carbon dioxide be absorbed within the metabolic chamber in order for the apparatus to work properly?

5. How would administration of propylthiouracil affect the metabolic rate of an otherwise normal individual?

And I also attach other question.
