Ivory, SEM

Ivory. Coloured scanning electron micrograph (SEM) of a fractured elephant tusk, which is the source of ivory. In ivory and teeth, there is an inner pulp cavity surrounded by dentine (purple), which is made up of connective tissue and collagen. The dentine is then covered in a bony layer called cementum and then enamel forms the outer layer. Dentine is the main component in ivory and it is this layer that is used for carvings and inlays. Magnification: x80 when printed 10 centimetres wide

Collagen Connective Dentine Elephant Fractured Ivory Substance Tusk False Coloured Section Sectioned

EDITORS COMMENTS
This print showcases the intricate details of an elephant tusk, the source of ivory. Taken using a scanning electron microscope (SEM), the image reveals a fractured surface that unveils the inner structure of this remarkable material. The purple-hued dentine, composed of connective tissue and collagen, surrounds an inner pulp cavity within both teeth and ivory. As we delve deeper into its composition, we discover that dentine is enveloped by a bony layer called cementum before being protected by enamel on the outermost layer. The magnified view provided in this photograph allows us to appreciate the complexity and beauty inherent in nature's design. With a magnification level of x80 when printed 10 centimeters wide, every minute detail becomes apparent to our curious eyes. It is worth noting that dentine serves as the primary component in ivory, making it highly sought after for various purposes such as carvings and inlays. This image not only provides insight into biological structures but also raises awareness about conservation efforts surrounding these magnificent creatures. Captured by Science Photo Library, this stunning SEM print offers a glimpse into the hidden world within an elephant tusk while reminding us of our responsibility to protect these majestic animals and their habitats for future generations.
