Fifteen amazing body shots captured using a scanning electron microscope,
showing incredible details of 1 to 5 nm (nanometers) in size.





1.  Red Blood Cells

They look like  little cinnamon candies here, but they're actually the most common type of  blood cell in the human body - red blood cells (RBCs). These  biconcave-shaped cells have the tall task of carrying oxygen to our entire  body; in  women there are about 4 to 5 million RBCs per micro liter (cubic  millimeter) of blood and about 5 to 6 million in men. People who  live at higher altitudes have even more RBCs because of the low oxygen  levels in their environment.   





2. Split End of  Human Hair

Regular  trimmings to your hair and good conditioner should help to prevent this  unsightly picture of a split end of a human hair.   





3.  Purkinje Neurons

Of  the 100 billion  neurons in your brain. Purkinje (pronounced purr-kin-jee)  neurons are some of the largest. Among other things, these cells are the  masters of motor coordination in the cerebellar cortex. Toxic exposure  such as alcohol and lithium, autoimmune diseases, genetic mutations  including autism and neurodegenerative diseases can negatively affect  human Purkinje cells.   





4.  Hair Cell in the Ear

Here's what it  looks like to see a close-up of human hair cell stereo cilia inside the  ear. These detect mechanical movement in response to sound  vibrations.





5.  Blood Vessels Emerging from the Optic Nerve

In this image,  stained retinal blood vessels are shown to emerge from the black-colored  optic disc. The optic disc is a blind spot because no light receptor cells  are present in this area of the retina where the optic nerve and retinal  blood vessels leave the back of the eye.





6.  Tongue with Taste Bud

This  colour-enhanced image depicts a taste bud on the tongue. The human tongue  has about 10,000 taste  buds that are involved with detecting salty, sour, bitter,  sweet and savory taste perceptions.  Thai people have very few --  most killed by eating spicy food.





7.  Tooth Plaque

Brush your  teeth often because this is what the surface of a tooth with a form of  corn-on-the-cob plaque looks like.





8.  Blood Clot

Remember that  picture of the nice, uniform shapes of red blood cells you just looked at?  Well, here's what it looks like when those same cells get caught up in the  sticky web of a blood clot. The cell in the middle is a white blood  cell.





9.  Alveoli in the Lung

This is what a  colour-enhanced image of the inner surface of your lung looks like. The  hollow cavities are alveoli; this is where gas exchange occurs with the  blood.





10.  Lung Cancer Cells

This image of  warped lung cancer cells is in stark contrast to the healthy lung in the  previous picture.





11.  Villi of Small Intestine

Villi in the  small intestine increase the surface area of the gut, which helps in the  absorption of food. Look closely and you will see some food stuck in one  of the crevices.





12.  Human Egg with Coronal Cells

This image is  of a purple, colour-enhanced human egg sitting on a pin. The egg is coated  with the zona pellicuda, a glycoprotein that protects the egg but also  helps to trap and bind sperm. Two coronal cells are attached to the zona  pellicuda.






13.  Sperm on the Surface of a Human Egg

Here's a  close-up of a number of sperm trying to fertilize an  egg.





14.  Human Embryo and Sperm

It looks like  the world at war, but it is actually five days after the fertilisation of  an egg, with some remaining sperm cells still sticking around. This  fluorescent image was captured using a confocal microscope. The embryo and  sperm cell nuclei are stained purple while sperm tails are green. The blue  areas are gap junctions, which form connections between the  cells.





15. Colored  Image of a 6 day old Human Embryo Implanting itself onto the wall of the  womb.
