Thyroid parafollicular cell, TEM
Thyroid parafollicular cell, coloured transmission electron micrograph (TEM). This section has revealed the cells nucleus (light brown). Also called a C-cell, this thyroid cell produces and secretes calcitonin, a hormone that controls blood calcium levels. The parafollicular cells are found in connective tissue (green) adjacent to the thyroid follicles. They are large and have a cytoplasm (red) containing numerous secretory granules (purple). Magnification: x5000 when printed at 10 centimetres wide

EDITORS COMMENTS
This print from Science Photo Library showcases a Thyroid parafollicular cell in stunning detail. The coloured transmission electron micrograph (TEM) reveals the intricate structure of this vital cell. The light brown nucleus stands out prominently, highlighting its significance as the control center for various cellular processes. Also known as C-cells, these thyroid cells play a crucial role in maintaining blood calcium levels by producing and secreting calcitonin, an essential hormone. Positioned adjacent to the thyroid follicles within connective tissue depicted in green, these large parafollicular cells exhibit a vibrant red cytoplasm that houses numerous secretory granules shown in purple. The high magnification of x5000 allows us to appreciate the complexity and beauty of this microscopic world when printed at 10 centimeters wide. This image not only provides valuable insights into human biology but also serves as a visual representation of health and normalcy. With its false-colored presentation, this histological masterpiece offers researchers and enthusiasts alike an opportunity to delve into the fascinating realm of cytology and endocrinology. It captures the essence of cellular function while showcasing the intricate interplay between hormones and their effects on our bodies. Science Photo Library continues to deliver exceptional images like this one that bridge artistry with scientific discovery, allowing us to marvel at nature's wonders on both macroscopic and microscopic scales.
