Abstract

This Learning Module takes you from an overview of the function of the thyroid gland to then hone in on the physiology of synthesis and secretion of thyroid hormone from amino acids and iodide, to its circulation in highly bound form in the circulation. Regulation of the concentrations are tightly regulated by the hypothalamus and pituitary. Understanding of diagnostic tests and treatment for the conditions of hypothyroidism and hyperthyroidism are discussed.
