Finger skin, SEM
Finger skin. Coloured scanning electron micrograph (SEM) of a section through skin from a human finger, showing the characteristic dermal ridges (lower left, and right) that make up the fingerprint. The epidermis (upper layer) is heavily keratinised. Magnification: x150 when printed 10 centimetres wide

EDITORS COMMENTS
This photo print, captured by Steve Gschmeissner from Science Photo Library, offers a mesmerizing glimpse into the intricate world of finger skin. Through the lens of a scanning electron microscope (SEM), we are presented with an awe-inspiring colored image that showcases a section of human finger skin in all its biological glory. The focal point of this image lies in the lower left and right corners, where the characteristic dermal ridges form what we commonly know as fingerprints. These unique patterns serve as our personal identification markers and play a crucial role in forensic science. As we explore further, our attention is drawn to the upper layer known as the epidermis. This outermost protective barrier exhibits heavy keratinization, indicating its robust nature. The magnification level used for this print allows us to appreciate these details at x150 when printed 10 centimeters wide. Delving deeper into cellular biology and cytology, this photograph sheds light on various cell layers within the epidermis and dermis. Keratinocytes take center stage here, showcasing their vital role in maintaining healthy skin through keratin production. In summary, Gschmeissner's remarkable work provides us with an exquisite visual representation of finger skin's anatomy and biology. It reminds us of both our individuality through fingerprints and the complexity hidden within even seemingly mundane aspects of our bodies.
