Get up close with innards of human body

Get up close with innards of human body with these amazing 3D-body shots.

All of the following images were captured using a scanning electron microscope (SEM), a type of electron microscope that uses a beam of high-energy electrons to scan surfaces of images.

The electron beam of the SEM interacts with atoms near or at the surface of the sample to be viewed, resulting in a very high-resolution, 3D-image.

Magnification levels range from x 25 (about the same as a hand lens) to about x 250,000.  Incredible details of 1 to 5 nm in size can be detected.

Blood Cell

1. 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.

Split End of Human Hair

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

Purkinje neurons

3. Of the 100 billion neurons in your brain. Purkinje 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.

Hair Cell in the Ear

4. Here is 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.

Blood Vessels Emerging from the Optic Nerve

5. 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.

Tongue with Taste Bud

6. 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 savoury taste perceptions.

Tooth Plaque

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

Blood Clot

8. 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.

Alveoli in the Lung

9. 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.

Lung Cancer Cellsl

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

Villi of Small Intestine

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

Human eggs with coronal cells

12. 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.

Sperm on the Surface of a Human Egg

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

Human Embryo and Sperm

14. It looks like the world at war, but it’s 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.

SpringerImages- A New Collection of Scientific and Medical Images

SpringerImages is a growing collection of scientific images that spans the scientific, technical and medical fields, including high-quality clinical images from images.MD. The continually updated collection – currently over 1.5 million images – gathers photos, graphs, histograms, figures, and tables, and is available to libraries and their patrons via a searchable online database. The SpringerImages interface enables users to search faster, more broadly and more accurately, through captions, keywords, context and more, even jumping from the image to the source article. Users can create personalized image “sets,” and can easily export images for use in their own presentations or lectures.

Yale Image Finder

YALE IMAGE FINDER is a search tool that allows you to look for images and figures from free full-text articles in the PubMed Central database of Open Access articles.

This tool debuted in July 2008 as a project of the Krauthammer Lab of the Yale Pathology Informatics Department that specializes in text mining and translational informatics.

The Krauthammer Lab published a paper that describes their search algorithm:

Krauthammer, M, McCusker, J, & Xu, S. (2008). Yale Image Finder (YIF): a new search engine for retrieving biomedical images. Bioinformatics, 24(17), 1968-70.

ABSTRACT: Yale Image Finder (YIF) is a publicly accessible search engine featuring a new way of retrieving biomedical images and associated papers based on the text carried inside the images. Image queries can also be issued against the image caption, as well as words in the associated paper abstract and title. A typical search scenario using YIF is as follows: a user provides few search keywords and the most relevant images are returned and presented in the form of thumbnails. Users can click on the image of interest to retrieve the high resolution image. In addition, the search engine will provide two types of related images: those that appear in the same paper, and those from other papers with similar image content. Retrieved images link back to their source papers, allowing users to find related papers starting with an image of interest. Currently, YIF has indexed over 140,000 images from over 34,000 open access biomedical journal papers.
