In this light microscope picture of some living Schwann cells rendered in colour through computer enhancement, the cell body of one cell appears reddish-brown and lies on top of another cell's process (light blue). Extending from the cell body is one of the main processes of the Schwann cell (they generally have two extending out in opposite directions). This process branches. Notice the very fine processes, especially mid-left in the image.
