Thyroid follicle structures. Coloured transmission electron micrograph (TEM) of a section through structures in a thyroid follicle. At lower right is the thyroid colloid (thyroglobulin,purple),which is a storage form of the thyroid hormones. The colloid is secreted by the follicle cells (green). Also seen are two capillaries containing red blood cells (erythrocytes,red). The grey and black structures are cell nuclei. Thyroid hormones regulate the body's metabolism.
