Neuron cell body (purple) with numerous synapses (blue). Communication from one neuron flows to another neuron across a synapse, the small gap separating neurons. SEM X80,000.

Inner ear hair cells, Scanning Electron Microscope. Coloured scanning electron micrograph (SEM) of sensory hair cells from the inner ear. These cells are surrounded by a fluid called endolymph. As sound enters the ear it causes waves to form in the endolymph, which in turn cause the hairs to move. The movement is converted to an electrical signal that is passed on to the brain. Each crescent-shaped arrangement of hairs lies atop a single cell.

It's pretty awesome to see an actual neuron and be able to identify it's components A neuron from the hippocampus at magnification. There are approximately 100 billion neurons in the human brain. Image by Dr. Carlo Sala, CNR Institute of Neuroscience

endothelial cells – Ovarian blood vessel, SEM

Coloured scanning electron micrograph (SEM) of a section through a blood vessel in an ovary. It is lined with endothelial cells (pink).

Wound scab. SEM of keratinocytes (red) at the site of a skin wound. Keratinocytes are skin cells that contain the protein keratin. They migrate to the site of a wound and form accumulating layers that form the hard protective object called a scab.

"Vodka Tonic" by Lester Hutt – Alcoholic drinks under a microscope: Just like images of snowflakes, each drink is different – What you can see in the magnified pictures are the crystallized carbohydrates that have become sugars and glucose.

The cancer cell's pink mitochondria and gold endoplasmic reticulum--a network of vesicles and sacs--swirl around a dark nucleus. The rendering was awarded an honorable mention in the illustration category of the 2008 International Science and Engineering Visualization Challenge.     Donald Bliss and Sriram Subramaniam of the National Institutes of Health's National Library of Medicine created the image by "sandblasting" the cell with ions of the element gallium.
