Small intestine, TEM
Small intestine. Coloured transmission electron micrograph (TEM) of a section through the wall of the small intestine. The surface consists of many small hair-like absorptive structures (red) called microvilli. These absorb nutrients from food as it passes through the lumen (internal space, blue, across top). The microvilli are the upper layer of the surface (epithelial) cells. These are columnar in shape (and so are called columnar epithelial cells). These cells (three seen here) extend down to lower centre, and the nuclei (yellow) are seen. Magnification: x600 when printed 10cm high

EDITORS COMMENTS
This print showcases the intricate details of the small intestine, as captured through a transmission electron microscope (TEM). The image reveals a section through the wall of this vital organ, highlighting its remarkable absorptive structures known as microvilli. These hair-like projections, depicted in striking red hues, cover the surface and play a crucial role in nutrient absorption from food passing through the internal space or lumen. The upper layer of cells forming these microvilli is composed of columnar epithelial cells. Their elongated shape gives them their name while enabling them to extend down towards the lower center. Within this mesmerizing snapshot, three such cells are visible along with their distinct yellow nuclei. With a magnification factor of x600 when printed at 10cm high, this false-colored TEM image provides an extraordinary glimpse into the microscopic world within our bodies. It offers insights into the biology and physiology behind digestion and intestinal function. This histological masterpiece not only serves as a testament to scientific advancements but also reminds us of how intricately designed our biological systems are. Captured by Science Photo Library, this print combines artistry with scientific precision to offer viewers an awe-inspiring visual experience that celebrates both anatomy and tissue exploration.
