What is a manifestation of excessive glucocorticoid production?
decreased immune response.
The mechanism of action of ipodate is to?
inhibit the release of T3 and T4 from thyroid cells.
Bradycardia, cold intolerance, hair loss and muscle pain are symptoms of?
hypothyroidism.
Radioactive iodine is often used for the treatment of hyperthyroidism. How would this treatment work?

The adverse effects of inappropriate glucocorticoid levels may include moon face, skin striae and abnormal fat distribution. These are considered to be?
= cushingoid effects (Cushings Syndrome)
Insulin is not directly involved in?
= glycogenolysis.
Which of the following statements is correct:
A. Thyrotropin releasing hormone is released from the pituitary to stimulate thyroid homone release.
B. Thyroid stimulating hormone is released from the pituitary in response to thyrotropin releasing hormone.
C. Thyrotropin releasing hormone release is increased by high circulating levels of thyroid hormones.
D. Thyroid stimulating hormone is released from the hypothalamus in response to being cold.
