It was, indeed, an SEM of a human hair. A damaged one that is, commonly known as a split end.
Part Ten: ?
These infectious little particles are responsible for transmissible spongiform encephalopathies; a group of fatal diseases that affect the brain and nervous system of many animals, including humans. But what are these nasties called? Bonus points for the abbreviation too…
There are only a few hours to go until the biggest Premier League match of the season. The potential title-decider between Manchester City and Manchester United at the Etihad Stadium.
Will we once again see Mario Balotelli lose the plot and spit out his dummy? Fergie will almost certainly be getting through an inordinate amount of chewing gum. But I doubt there’ll be much love lost between the red and blue sides of Manchester this evening.
Scanning electron micrograph of two *nerve fibres*. The individual *axons* sit within their myelin sheaths (green) and are packed with energy producing mitochondria. The myelin provides a layer of electrical insulation made up of lipids and proteins produced by the Schwann cells.
Nobody wins a print this week. Oh well, we’ll just stick it up in our office instead. Lucky we’re a fan of the nerve cell.
Let’s see if this is any easier…
Part Eight: ?
Clues: 1. This thing packages proteins inside the cell. 2. Because it’s big, it was one of the first organelles to be discovered. 3. By a man called Camillo. 4. Made up of flattened membrane disks called cisternae.
Saliva! Remember, gobbing in the street can lead to tuberculosis so don’t do it.
Part Seven: ?
Back to GCSE Biology. Fill in the missing words:
Scanning electron micrograph of two _____ _____. The individual _____ sit within their myelin sheaths (green) and are packed with energy producing mitochondria. The myelin provides a layer of electrical insulation made up of lipids and proteins produced by the Schwann cells.
It’s Friday the 13th, but are you superstitious enough for it to be affecting your day? Perhaps you think it’s just a load of nonsense and nothing to worry about? This study, published in the BMJ in 1993, seems to suggest that it really might be riskier than normal to leave the relative safety of your home on such days.
Whichever side you’re taking, I’m sure you’ll appreciate this image of a Japanese ivory figure, or netsuke. It’s in the form of the racoon dog Tanuki, commonly associated with gluttony and excessive drinking - but also a bringer of good luck. Let him (and his grossly enlarged scrotum) see you safely through the night into Saturday the 14th.

And here is this week’s image. If you think you come up with captions just as brilliant as ours, tweet them to us @wellcomeimages for a chance at fame and glory. Well, we’ll post it up here. That’s the best we can do.
Last week’s kelideoscope of colour was…urea crystals! A polarised light micrograph of urea crystals to be precise. Urea is produced in the liver to remove toxic ammonia from the body, travelling in the blood to the kidneys where it is then excreted via the bladder as a component in urine. Nice.
Are you ready for today’s?
Part Five: ?
Here at Wellcome Images we rate this as one of our favourite organelles; if it were a factory it would manufacture proteins.
This particular image is a 3D reconstruction of villi in the small intestine of the mouse. The image was created from a whole mount with a fluorescent stain applied to mark different cellular components. The tips of the villi have been cropped away to show the internal morphology; actin on the surface of each villus is stained red and cell nuclei are labelled blue.
Part Four: ?
These are crystals of an organic compound produced in the liver and used by the body during the excretion of nitrogen.
With temperatures soaring way above what we’d normally expect in mid-March, what better way to relax and cool down after a hard week of work than with a refreshing drink of milk. Straight from the teat of the beast…
Did you guess correctly? Last week’s was, of course, blood vessels belonging to the liver!
But what is this?
Part Two: ?
These cells are packed full of mucin (blue) which one secreted dissolve in water to form mucus, providing lubrication and protection to the epithelial lining of organs, including the intestinal and respiratory tracts.
Can you guess what it is yet?
Let us know via Twitter - @wellcomeimages - and you could win the image. Amazing!

Just as our eponymous founder had a penchant for collecting weird and wonderful items from around the world (you can see some at Wellcome HQ right now), so too are there some rather intriguing pictures to be found within Wellcome Images.
We’ll begin with the quirky and go from there. If it’s all too mainstream and passée, let us know and we’ll up the ante. So, what better way to kick things off than with some anthropomorphic animals (-that’s critters doing people things, in case you hadn’t already worked it out).
This image of a well-dressed pair of thirsty orang-utans could well have been the inspiration for a major tea company’s advertising campaign.
But as far as I’m aware, no baboon has yet put its face to any tobacco products.
And finally, showing us that being told that you ‘eat like an animal’ need not be an insult, two impeccably attired elephants demonstrate the very best in alfresco fine-dining.
In memory of our benefactor Sir Henry, Wellcome Images brings you a blog full of crazy cats from the furriest depths of our archives. You can read all about Henry’s love of cats here.
Each week we want you to come up with the most amusing image caption you can think of and tell us on Twitter (@wellcomeimages). The wittiest caption will be incorporated into the image and posted on our blog next week. Have a look at Lolcats for some inspiration!
This week we’re kicking off some exciting new strands, and to get us going something a little interactive.
Each Monday we’ll post an intriguing image from our Biomedical Collection. Let us know what you think it is via Twitter (@wellcomeimages) and you could be the lucky recipient of the image in glossy print format (or matt - your choice). Exciting stuff for a Monday, I know! Don’t worry we’ll provide some clues.
And to plagiarise the words of our favourite Australian entertainer, Rolf Harris, we’re naming it Can you guess what it is yet?
Part One: ?
These are blood vessels inside a vital organ, but do you know which one?
The yellow bits are hepatic portal veins and the red bits centrolobular vessels.
Absorbed nutrients from the intestine arrive here via the hepatic veins. Processed products collect in the centrolobular vessels and are transported away to other destinations.
