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.
This is actually human hair, but not in its best shape. In the image, the hair is with a split end.
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.
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.
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.
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.
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.
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.
For those who don’t know, this is what exocrine pancreatic cells look like, responsible for releasing pancreatic juice, which contains digestive enzymes.
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!
