Fat tissue. Coloured scanning electron micrograph (SEM) of a sample of fat tissue, showing fat cells (adipocytes, blue) surrounded by fine strands of supportive connective tissue. Adipocytes are among the largest cells in the human body, each cell being 100 to 120 microns in diameter. Almost the entire volume of each fat cell consists of a single lipid (fat or oil) droplet. Adipose tissue forms an insulating layer under the skin, storing energy in the form of fat, which is obtained from…

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.

Staphylococcus bacteria. Coloured scanning electr- on micrograph (SEM) of Staphylococcus aureus bacteria (yellow) on human nasal epithelial cells. These gram-positive cocci (spherical bacteria) are adhering to mucus (blue) on the hair-like cilia which protrude from the epithelial cells. S. aureus is very common in humans, living harmlessly on the skin and in the nose, throat and large intestine. Science is Everything (Staphylococcus bacteria. Coloured scanning electr-...)

This is a different perspective on a paramecium protozoan than I saw in high school.  ...I like it.

I love how you can see the cells embedded in/passing through the vein wall. Ruptured venule under scanning electron microscope.
