Nerve cell and axon, diagram
Nerve cell and axon. Diagram showing how the input to a nerve cell (neuron) through dendrites (shown by arrows at upper left) is transmitted (yellow arrow) along the nerve cells axon (across bottom) to the axon terminal (upper right). At lower centre, part of the axon has been illustrated in cutaway form to show the internal structure of the individual sections, including the myelin sheath. The myelin sheath is brown in the main artwork and red in the cutaway section. These sections are joined at junctions called nodes of Ranvier. Also shown is the nucleus of a Schwann cell (bump on cutaway section at left)

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate structure of a nerve cell and its axon, providing a glimpse into the fascinating world of neuroscience. The diagram illustrates how information is transmitted within a neuron, starting with inputs received through dendrites at the upper left corner. These inputs are then conveyed along the axon, depicted by a vibrant yellow arrow that stretches across the bottom of the image until it reaches the axon terminal at the upper right. To offer further insight into this complex system, part of the axon has been illustrated in cutaway form at lower center, revealing internal structures such as individual sections and their myelin sheaths. In this artwork, these sections are beautifully portrayed in brown while being accentuated with red in the cutaway section. Notably present are junctions called nodes of Ranvier which connect these sections together. The nucleus of a Schwann cell can also be observed as a bump on the cutaway section's left side - an essential support cell for proper functioning. This illustration provides valuable visual representation to aid comprehension in fields like biology, neurology, and physiology. Overall, this print serves as an educational tool that highlights both cellular and physiological aspects related to nerve cells' ability to transmit electrical signals throughout our neural network. It offers viewers an opportunity to appreciate not only its scientific significance but also its artistic beauty.
