Nerve bundle. Coloured scanning electron micrograph (SEM) 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.
Colored scanning electron micrograph (SEM) of squamous cell carcinoma (cancer) cells from a human mouth. The many blebs (lumps) and microvilli (small projections) on the cells' surfaces are typical of cancer cells.
The Astounding And Horrific World As Seen Under A Microscope
An image of a hydrothermal worm taken at 525 times magnification under a scanning electron microscope. No photoshopping. Hydrothermal worms are deep sea creatures, almost as small as bacteria, and are largely found near hydrothermal vents in the ocean.
