Question
Chapter 11, Problem 22RA
Summary Introduction
To review:
The effect of a drug which blocks the conversion of T4 into T3 on TSH secretion, thyroxine secretion, and size of the thyroid gland.
Introduction:
The hypothalamus has the task of secreting thyrotropin-releasing hormone (TRH) to stimulate the anterior pituitary gland to release thyroid-stimulating hormone (TSH). The thyroid gland is triggered by TSH to release thyroxine or tetraiodothyronine (T4) and triiodothyronine (T3). The secreted thyroxine and triiodothyronine are transferred to the target sites through the bloodstream.

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).
Thyroid secretes all of the following hormones, except:A. ThyrotropinB. CalcitoninC. ThyroxineD. DiiodotyrosineE. Triiodothyronine
Obtain a prepared slide of the thyroid. Scan the thyroid under low power, noting the follicles, spherical sacs containing a pink-stained material. The parafollicular, or C cells you see between the follicles are responsible for calcitonin production and explain what have you observe.
