Nerve fibre node, TEM C014 / 1458
Nerve fibre node. Transmission electron micrograph (TEM) of a longitudinal section through a nerve fibre at a node of Ranvier, showing the nerve tissue (red) and the myelin sheath (dark blue). The myelin sheath is absent at a region known as a node of Ranvier (far left). Myelin is an insulating material that increases the speed of conduction of nerve impulses. The exposed areas at the nodes of Ranvier contain many sodium channels, allowing nerve impulses to start and propagate between these nodes, a process called saltatory conduction. This regenerates a nerve impulse, allowing it to travel over long distances. Magnification: x8000 when printed 10cm wide

EDITORS COMMENTS
This print showcases a nerve fibre node in all its intricate glory. Captured using a transmission electron microscope, the image reveals the inner workings of a nerve fibre at a node of Ranvier. The vibrant red represents the nerve tissue, while the dark blue signifies the myelin sheath that envelops it. Interestingly, at this specific region known as a node of Ranvier, the myelin sheath is absent. This absence allows for an essential process called saltatory conduction to occur. Saltatory conduction involves the propagation of nerve impulses between these nodes, regenerating and enabling them to travel over long distances within our nervous system. The exposed areas at these nodes play a crucial role in this process as they contain numerous sodium channels. These channels facilitate the initiation and continuation of nerve impulses, ensuring their efficient transmission throughout our body. Myelin itself acts as an insulating material that significantly increases the speed of conduction for these nerve impulses. Its presence along most parts of the fibre enhances efficiency by preventing signal loss or interference. Through this remarkable visual representation captured at x8000 magnification when printed 10cm wide, we gain insight into one aspect of human anatomy and physiology that underlies our complex neurological system. It serves as a testament to both biological beauty and scientific discovery.
