Thyroid gland, SEM C015 / 6419
Thyroid gland. Coloured scanning electron micrograph (SEM) of a fracture through the thyroid gland revealing several follicles (green and blue). Between the follicles is connective tissue (pink). A follicle consists of a layer of epithelial cells around a central storage chamber. The cells produce the thyroid hormones tri-iodothyronin (T3) and thyroxine (T4) and secrete them into the central chamber where they are stored as the glycoprotein thyroid colloid. Thyroid hormones regulate the bodys metabolism

EDITORS COMMENTS
This print showcases the intricate beauty of the thyroid gland, a vital component of the human body's endocrine system. Through a colored scanning electron microscope (SEM), we are granted an up-close view of a fracture that exposes several follicles within the gland. The follicles, depicted in shades of green and blue, are surrounded by connective tissue presented in pink hues. Each follicle consists of a layer of epithelial cells encircling a central storage chamber. These remarkable cells play a crucial role in producing essential thyroid hormones such as tri-iodothyronine (T3) and thyroxine (T4). As highlighted by this image, these hormones are secreted into the central chamber where they are stored as glycoprotein thyroid colloid. The presence and regulation of these hormones directly impact our body's metabolism. By delving into this microscopic world, we gain insight into the complex workings of our own bodies. This SEM image not only serves as an educational tool for those studying biology or anatomy but also offers us all an opportunity to appreciate the wonders hidden within ourselves.
