Question
Chapter 18, Problem 12CP
Summary Introduction
To explain:
The changes in the blood levels of triiodothyronine (T3), thyroxine (T4), TSH (thyroid-stimulating hormone), and TRH (thyrotropin-releasing hormone) in the animal, which has had a complete thyroid gland removal.
Introduction:
The thyroid hormones are released from the thyroid gland that is located below the larynx. The thyroid hormones are T3 and T4 and they contain iodine. They are lipid-soluble hormones. As a result, they are involved directly in protein synthesis and gene transcription.

Explain how blood levels of T3/T4, TSH, and TRH would change in a laboratory animal that has undergone a thyroidectomy (complete removal of its thyroid gland).
Describe the functions of the following hormones: TSH, thyroxine, calcitonin, PTH, ACTH, cortisol, insulin, glucagon, hGH, ADH, epinephrine, and aldosterone.
Most laboratories are able to determine blood levels of TSH, T3,and T4. Given that ability, design a method of determining whetherhyperthyroidism in a patient results from a pituitary abnormality or from the production of a nonpituitary thyroid stimulatorysubstance.
