The human body under a microscope (23 images)

John Henrique Nov 13, 2020

The advances in microscopy over the past century have given us an unprecedented view of the universe on a tiny scale.

Everything can look strange under a microscope, even the human body. Below we have put together a list of images of different parts of the human body under the microscope. Some have been increased up to 5,000 times!

1. Red blood cells

Red blood cells are responsible for transporting oxygen throughout the body.

2. Hair

This is actually human hair, but not in its best shape. In the image, the hair is with a split end.

3. Neurons

This is one of the most important cells in the human body. Neurons are located in the brain and are responsible, among other things, for our motor coordination, our memory, and the ability to learn new information. In the image, you can see Purkinje neurons, much larger than usual.

4. Hair cells of the ear

Also called stereocilia, these cells are located inside human ears. They help to detect mechanical movements as a result of sound vibrations.

5. Retina

This image shows what the human retina looks like. The blood vessels appear coming out of the optic disc, which is the black part. The optic disc itself, however, appears as a blind spot, as there are no light-receiving cells in this region of the retina.

6. The tongue

Although it looks scaly and rough under the microscope, this is how the human tongue really is.

Below, another image shows the taste bud, the red balls in the first image.

According to scientific literature, every human being has 10,000 taste buds, which help us to identify the different flavors of food.

7. Tooth

This image shows, under the microscope, what a human tooth with dental plaque looks like. Better to keep your teeth well brushed now that you know how it looks, don’t you think?

8. White blood cell

This is another type of cell found in our blood. In the image, you can also see what happens when red blood cells are trapped in the collagen (that part that looks sticky) of the blood.

9. Lung

This is what the surface of your lung looks like, if you are not a smoker, of course. The cavities shown in the image are alveoli, which allow the exchange of gases with the blood.

10. Small intestine

This is the lining of the small intestine. These structures help in absorbing nutrients from food.

11. Egg cell

In the image, you can see an egg cell many times bigger than it actually is. There is a coating that allows sperm to stick to its surface. Attached to this coating are two coronal cells.

13. Egg and sperm

This is what a woman’s egg looks like when sperm are trying to fertilize it.

14. Fertilized egg

In the image, the egg has 5 days of fertilization and some sperm are still around it.

15. Embryo

In this image, it is possible to see the beginning of a new life: a 6-day embryo. It is implanted in the endometrium, the uterine wall.

16. Cancer cell

In this image, the cancer cell is dividing. The irregular surface, which can be seen in bluish colors, are structures responsible for the movement of these cells.

17. Human bone

This is what a human bone with osteoporosis looks like under a microscope. Notice the voids in the bone structure and the porous texture it has.

18. Skin

This is what your beautiful skin looks like up close. On the surface, it is possible to notice a good amount of dead skin, which will be replaced naturally by your body.

19. Fat tissue

Also known as adipose tissue. In addition to the fat cells, full of lipids (in green), it is also possible to see fat-free cells, which are empty.

20. Uterine tubes

This is the lining of the fallopian tubes, which connect the ovaries to the uterus in a woman’s body.

21. Pancreas

For those who don’t know, this is what exocrine pancreatic cells look like, responsible for releasing pancreatic juice, which contains digestive enzymes.

22. Tendon

In the image, enlarged 5,000 times, it is possible to see the bundles of collagen fibers.

23. Blood vessels

These blood vessels, in particular, are located in the pulmonary alveoli, just at the end of the bronchioles.

The human body is truly impressive – on every scale!
