Image of a nerve bundle supplied by scientific photographer Steve Gschmeissner, from Bedford in the UK. The image is a colored scanning electron micrograph of a freeze-fractured section through a bundle of myelinated nerve fibres. Myelin sheaths (yellow) can be seen surrounding the axons (blue). Perineurium (connective tissue, pink) surrounds the nerve bundle while endoneurium divides the individual fibres. Magnification: x1650 when printed 10 centimeters wide. As a side note, Steve needs your help: “I have a number of unidentified micrographs from an excellent histopathology collection of unlabeled slides that I’ve photographed. If anybody would like to take on the challenge of helping me, please email s.gschmeissner@ntlworld.com.”
