Eyelash, SEM
Eyelash, coloured scanning electron micrograph (SEM). Eyelashes are hairs that grow from the eyelids. They are sensitive to being touched, providing a warning that an object is near the eye, which is then closed reflexively to prevent foreign bodies from entering the eye. Hairs grow from follicles in the underlying layer of skin (the dermis), and are mainly composed of the protein keratin. Squamous skin cells are also seen flaking off the surface of the skin, and adhering to the shaft of the eyelash. Magnification: x350 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate details of an eyelash, captured using a scanning electron microscope (SEM). Eyelashes, which grow from our eyelids, serve as a protective mechanism for our eyes. They possess sensitivity to touch and act as warning signals when objects approach too close to the eye. This reflexive response prompts us to instinctively shut our eyes, preventing foreign bodies from entering. The hairs on this eyelash emerge from follicles in the underlying layer of skin called the dermis. Composed primarily of keratin protein, they exhibit a remarkable structure under magnification. Additionally, squamous skin cells can be observed flaking off the surface of the skin and adhering to the shaft of the lash. With a magnification level of x350 when printed at 10 centimeters wide, this SEM image offers an extraordinary glimpse into the biology and anatomy of human lashes. It highlights not only their functional role but also provides insight into their composition and relationship with surrounding tissues. This photograph is part of Science Photo Library's collection that delves deep into various aspects of cell biology, human anatomy, and microscopic details within our bodies. Its scientific significance lies in its ability to shed light on these fascinating biological structures while showcasing their aesthetic beauty simultaneously.
