Myelinated nerves, SEM C013 / 7142
Myelinated nerves. Coloured scanning electron micrograph (SEM) of a section through the sciatic nerve, showing the myelinated nerve fibres (axons). Myelin (blue) is an insulating fatty layer that surrounds the nerve fibre (brown), increasing the speed at which nerve impulses travel. It is formed when Schwann cells wrap around the fibre, depositing layers of myelin between each coil. The outermost layer consists of the Schwann cells cytoplasm and is known as the neurolemma or sheath of Schwann. Magnification: x1350, when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of myelinated nerves, offering a glimpse into the complex world of our nervous system. Taken using a scanning electron microscope (SEM), this colored image depicts a section through the sciatic nerve, revealing an array of myelinated nerve fibers or axons. The blue hues represent myelin, an insulating fatty layer that envelops and protects each nerve fiber. This crucial sheath is responsible for enhancing the speed at which nerve impulses travel throughout our body. The process of myelination occurs when Schwann cells wrap around the fiber, meticulously depositing layers of myelin between each coil. At x1350 magnification, this print captures even the tiniest details with remarkable clarity. It measures 10 centimeters wide when printed and serves as a testament to both scientific advancement and artistic appreciation. By delving into this mesmerizing image, we gain insight into how our neurons are structured and function within our biological systems. It reminds us of the incredible complexity underlying even seemingly simple bodily functions. Whether you're fascinated by biology or simply appreciate stunning visual representations of nature's wonders, this print is sure to captivate your imagination and spark curiosity about the inner workings of our nervous system.
