Illustration of follicles in the thyroid gland
Thyroid gland. Illustration of the microscopic cell structure of the human thyroid gland, with an outline of the whole gland superimposed. The white outline (at centre) represents the shape of the thyroid gland, located in the neck. Its cellular structure (background) consists of round follicles which produce thyroid hormone. Cut through, the follicles are composed of cuboidal epithelial cells (purple) which secrete hormones (light blue) into a central storage chamber. Each follicle is surrounded by a network of blood capillaries (red) which transport secreted thyroid hormone in the blood to the rest of the body. Nerves are yellow. Thyroid hormones control metabolism and growth

EDITORS COMMENTS
This print showcases the intricate and vital structure of the thyroid gland. The illustration beautifully depicts the microscopic cell arrangement within this endocrine gland, which plays a crucial role in regulating metabolism and growth in the human body. At the center of attention is a white outline representing the shape of the thyroid gland, nestled in our necks. Surrounding it is an array of round follicles that are responsible for producing essential thyroid hormones. These hormones, depicted as light blue secretions, are diligently released into a central storage chamber by cuboidal epithelial cells shown in purple. The significance of this process becomes evident as we observe the network of blood capillaries portrayed in red encircling each follicle. These capillaries serve as conduits, transporting these precious thyroid hormones throughout our bodies via our bloodstream. Highlighted against this complex backdrop are yellow nerves, emphasizing their connection to this remarkable gland's functionality. Through its meticulous detail and vibrant colors, this artwork from Science Photo Library not only captures scientific accuracy but also evokes awe at nature's intricacy. It serves as a reminder that even on such a minuscule scale within our bodies lies an extraordinary system governing fundamental aspects of our well-being – metabolism and growth.
