IT IS THE PURPOSE OF THIS PAPER to review recent developments in the biochemistry
and physiology of the thyroid gland in normal and pathologic states. The reader is referred to …

Thyroid hormone (TH) plays a critical role in maintaining metabolic homeostasis throughout
life. It is well known that the liver and thyroid are intimately linked, with TH playing important …

Close relationships exist between the liver and the thyroid. The liver is important in the
transport, metabolism, storage and excretion of thyroid hormones as well as being an …

Thyroid hormones (TH) are essential for normal development, differentiation growth and
metabolism of every cell in the body. The pro-hormone thyroxine (T4) is synthesized by the …

I. Introduction N ORMAL growth and neurological development are dependent on a normal
metabolic state, conditioned by an adequate supply of thyroid hormones. Synthesis of T3 …

• About 93 per cent of the metabolically active hormones secreted by the thyroid gland is
thyroxine, and 7 per cent triiodothyronine.• Thyroxine is eventually converted to …

The thyroid follicular cells encircle a central store of colloid. Multiple attached follicles give
an appearance of frog's eggs when viewed in three dimensions. These cells are principally …

The endocrine glands and hormones constitute a major control system for the maintenance
of homeostasis in man. The thyroid gland, as one prototype, may be considered as an organ …

The pathway through which thyroid hormone controls metabolism begins with secretion of
thyroxine and triiodothyronine by the thyroid, peripheral deiodination of about 1/3 of …

Publisher Summary This chapter examines various aspects of thyroid regulatory processes
and discusses thyrocalcitonin. In context to thyroid hormone regulation, thyrotropin-releasing …
