Spinal cord, SEM
Spinal cord. Coloured scanning electron micrograph (SEM) of a section through a spinal cord, showing the grey matter (green) and white matter (blue). The spinal cord begins at the base of the brainstem, and extends down to the space between the first and second lumbar vertebrae. It consists of two distinct areas: grey matter, which contains the nerve cell bodies; and white matter, which contains the myelinated nerve fibres (axons). Magnification: x30 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of the spinal cord, as captured by Steve Gschmeissner. In this coloured scanning electron micrograph (SEM), we are provided with a detailed view of a section through the spinal cord, revealing its remarkable composition. The image displays two distinct areas: grey matter and white matter. The green hue represents the grey matter, which houses nerve cell bodies responsible for processing sensory information and controlling motor functions. On the other hand, the blue shade symbolizes white matter, consisting of myelinated nerve fibres or axons that transmit signals between different parts of our body. Stretching from the base of the brainstem to between the first and second lumbar vertebrae, this vital structure is an integral part of our central nervous system (CNS). It plays a crucial role in relaying messages between our brain and body, allowing us to move, feel sensations, and perform various bodily functions seamlessly. Gschmeissner's expertise in microscopy enables us to appreciate both the complexity and elegance hidden within our own anatomy. This stunning visual representation serves as a reminder of how intricately designed our internal systems are while highlighting their inherent beauty.
