Once synthesized, thyroid hormones are stored as part of thyroglobulin in which area of the thyroid gland?

Explanation:
Hormone storage happens in the colloid inside the thyroid follicle. Thyroglobulin, produced by follicular cells, is released into this colloid-rich lumen, where iodine is added to tyrosine residues to form the iodinated thyroid hormones. The hormones stay bound to thyroglobulin in the colloid as a reservoir until a signal (like TSH) triggers endocytosis and proteolysis to release T3 and T4 into circulation. So the correct site is the colloid within the follicle.
