WebbThyroid Gland Located in the neck and partially enwrapping the trachea, the richly vascularized thyroid consists of large numbers of small thyroid follicles embedded in a connective tissue stroma. Each follicle is lined by a simple cuboidal epithelium, and the cavity is filled with a material commonly called colloid (Fig. 9.9 ). Thyroid follicular cells (also called thyroid epithelial cells or thyrocytes ) are the major cell type in the thyroid gland, and are responsible for the production and secretion of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). They form the single layer of cuboidal epithelium that makes up the outer structure of the almost spherical thyroid follicle.

Webb1 Introduction. The thyroid gland contains two populations of epithelial cells, of quite different embryological origin and function. Only the major component—the follicular cells—is considered here. The minor C cell population, which forms only a few percent, can be ignored for the purposes of primary culture. Webb1 Introduction.

Webb21 apr. 2024 · The thyroid epithelial cells vary in the physiological range in form depending on the degree of activation, when under normal conditions they are cuboidal epithelium (Fig. 5.4), whereas activated they become vertical/columnar (Fig. 5.5) and flat on inhibition (Fig. 5.6). All these variations are within the physiological limits. photography subscription box uk
