The thyroid gland is a butterfly-shaped structure, situated directly below the larynx at the midline of the anterior neck, with the gland’s two lobes on either side of the larynx attached by the isthmus. This gland is made up of a multitude of very small saclike structures referred to as follicles. These follicles are the functional aspect of the thyroid gland; they are made with a solitary coat of epithelial cells and are filled with a secretory material called colloid. This material is comprised mainly of a glycoprotein-tyrosinc compound, specifically thyroglobulin. This substance that functions in filling the thyroid particles is a big glycoprotein molecule that contains 140 tyrosinc amino acids. When the thyroid is synthesized, iodine attaches to these tyrosinc molecules and both thyroglobulin and iodide are secreted into the colloid of the follicle. This secretion is accomplished through the
