Using a Scanning Electron Microscope, retired scientific photographer Steve Gschmeissner, 61, from Bedford, is able to magnify insects by up to a million times. The results show incredibly detailed images of creepy crawlies in 3D A coloured scanning electron micrograph of the head of a human flea (Pulex irritans)
Nerve cells. Coloured scanning electron micrograph (SEM) of nerve cells, known as neurones. Nerve cells occur in the brain, spinal cord, and in ganglia. Each nerve cell has a large cell body (brown) with several long processes extending from it. The processes usually consist of one thicker axon and several thinner branched dendrites. The dendrites collect information in the form of nerve impulses from other nerve cells and pass it to the cell body.
