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
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
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 budsthat
are involved with detecting salty, sour, bitter, sweet and savory taste
7. Tooth Plaque
Brush your teeth often because this is what
the surface of a tooth with a form of â€œcorn-on-the-cobâ€� 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.
