A very important "What the Fox Say?" parody by students from the 2016 class of Harvard Medical School and Harvard School of Dental Medicine.
And, for the record, the spleen is involved in filtering blood and recycling red blood cells and also serves as a storage reserve of white blood cells. Now you know.
This video was made by the University of Utah Brain Institute to teach medical students about what a brain looks and feels like before it gets preserved in formalin and takes on the texture of a hard rubber ball.
The big takeaway message: Your brain is seriously squishy. So squishy, in fact, that a finger can dent it. As professor Suzanne Stensaas explains, this is one of the reasons why cerebrospinal fluid is so important. Your brain has to float in that fluid. If it didn't, it would come to rest against the side of your hard skull and quickly end up deformed.
Seriously, this is a fascinating (if extremely graphic) video. (Hilariously, given that fact, it opens with an image of a student eating.) Definitely worth watching!
A mere $40K gets you Syndaver's full-body practice cadaver, a beautifully detailed surgical simulator, with "skin with fat and fascia planes, every bone, muscle, tendon, and ligament in the body, fully articulating joints, a functioning respiratory system including trachea, lungs, and diaphragm, a complete digestive tract from the esophagus to rectum, the urinary tract (kidneys, bladder, and urethra), visceral organs (liver, gall bladder, pancreas, spleen), reproductive organs, a circulatory system with heart and coronary arteries, aorta, vena cava, and the primary arterial and venous trunks leading to the extremities."
They call it "pinnacle of hands-on surgical simulation" and "a 3D jigsaw puzzle" -- and who am I to argue. If $40K is too rich for your synthetic blood, they also do organs, wearable simulators for training roleplay, synthetic tissues, and a whole range of delightful wobbly bits.

The Fabric of the Human Body: Spectacular edition of foundational 16th C anatomy text, 20 years in the making
Read the rest
David Hast sez, "Karger Publishing has released an important new translation of a foundational book in the history of science, the 16th century 'De Humani Corporis Fabrica Libri Septem' by Andreas Vesalius. Vesalius was the first modern anatomist, relying for the first time in history on dissections of human cadavers. His anatomy is a foundation of modern medicine and of the understanding of the human body."

Lisa Nilsson creates breathtaking anatomical cross-sections from paper. She has a new exhibition opening tomorrow at New York City's Pavel Zoubok Gallery. From Nilsson's artist statement:
These pieces are made of Japanese mulberry paper and the gilded edges of old books. They are constructed by a technique of rolling and shaping narrow strips of paper called quilling or paper filigree. Quilling was first practiced by Renaissance nuns and monks who are said to have made artistic use of the gilded edges of worn out bibles, and later by 18th century ladies who made artistic use of lots of free time.Lisa Nilsson: "Tissue Series" (via Juxtapoz)
Artist Kate Lacour created a set of reflected anatomical drawings that are one part miracle-of-the-guts, one part split-and-matched veneer (with some NSFW for added awesome). They're gorgeous, grotesque, and wonderful. Alas, she's not selling prints -- maybe someday!
Update: Hurrah, prints are for sale!
This 1863 image from the Wellcome Trust illustrates a distinctly vampiric set of "Syphilitic malformations of the permanent teeth" -- makes you wonder if the visual image of the vampire was inspired by the widespread horrors of untreated syphilis (for an exceptionally visceral window into a society wracked by untreated syphilis, have a look at the Mutter Museum's display of syphilitic skulls).
Can you properly distinguish between a male and female crocodile? This research paper, published in 2007, will help — pointing out the sometimes subtle differences between external genitalia. It's chock full of pictures of erect crocodile penises, so you'll learn what those look like, but what particularly interested me was the diagram above.
Cloacas are sort of multi-purpose orifices found in certain species of birds and reptiles. Instead of having separate biological tools for poop, pee, and sex, these animals manage all three functions with the same hole. Males also have cloacas and will either have a penis or pseudo-penis that comes out of it for mating. I've known this for a long time, but had a lot of trouble picturing how all of that anatomy fits together. This diagram (Figure 4 in the paper) is the first image that made the internal structure of cloacas really make sense to me. The more you know!

Today's horrible, crushing disappointment comes to you from Etsy seller GreatWhiteVintage, who discovered this vintage anatomical sweatshirt with a flap showing the brains-n-stuff, and then sold it to someone else.
A bar in the Yukon needs to source a new human toe, because a patron ate the one they used to use as a cocktail garnish.
The sourtoe cocktail was legendary at the Downtown Hotel in Dawson City. Over 52,000 people have drunk cocktails garnished with toes at the bar, and were on notice that they faced a $500 fine if they swallowed the toe. But two weeks ago, a mysterious stranger stepped into the bar, ordered the sourtoe, drank it down, toe and all, plunked $500 on the bar, and walked out into the night.

This pair of striking images of teeth colonized by ambitious antiquarian architecture are part of a campaign for Maxam toothpaste from JWT Shanghai; the slogan is "Don't let germs settle down."
A 2011 entry from the Museum of Sex by Melodiousmsm explores the internal anatomy of the clitoris, whose extent wasn't fully mapped until 2005, when Royal Melbourne Hospital urologist Helen O'Connell published her groundbreaking MRI studies. The clitoris forks internally like a wishbone, and then ramifies further. As Melodiousmsm notes, this suggests that the argument over vaginal versus clitoral orgasm has been misplaced, since the clitoris runs through the vulva and vagina.
The most interesting part of this article are the longstanding misperceptions about clitoral anatomy, the fact that science understood so little about such a significant organ for so long. The clitoris, after all, is the only organ that exists purely for the purpose of conveying pleasure, and has as much erectile tissue as a penis, but somehow it was mostly missed for literally millennia.

Circumcision training kit, fake gangrenous feet, fake blood, artificial fat, aged torsos & artificial earwax: the wonderful world of Life/Form trainers
Life/Form's $186 circumcision trainers "include the foreskin, glans penis, frenulum, meatus, and coronal groove" and are "made with our soft, lifelike material, which is pliable, delicate, and realistic to the touch."
More seriously, Life/Form sells a pretty amazing range of anatomical models for training and education, including a 1lb lump of fat (also sold by the ounce and the five-weight); artificial blood by the quart; gangrenous, ulcerated feet; lifelike bedsores; obese, geriatric head/torso mixes; jars of artificial earwax, and much, much more.

A paper in Royal Society Biology Letter by University of Toronto biologist Lucia Kwan describes the strange, adversarial clawed sex-organs of some guppies. Kwan experimented with shaving the barbs off of the penises of some male guppies to investigate the relative advantages of claws for mating with "unreceptive females." She concluded that the claws were a "sexually antagonistic trait" that evolved to allow males to force females to mate with them.

When I blogged Leslie Arwin's Skeletees in 2007, I had no idea that I'd still be wearing my Skeletee all the time, six years later. But it seems like I wear it at least once every couple weeks, despite my massive trove of shirts. She does a gorgeous muscle tee, too, and many other designs:
Medical illustrator Leslie Arwin's Skeletees feature highly detailed, stark anatomical drawings of the bones, muscles, nerves and digestive tract, printed on the front and back. I picked up a skeleton shirt today and I'm delighted with it -- it's a great, thick, high-quality tee with a nice cut and the design is wonderful.

You know what you missed? You missed the chance to buy this amazing set of vintage derpface choppers ("Authentic original used dental school teaching device."), which sold on eBay for $400.
Everything a dissection table should be, I suppose. I'm absolutely mesmerized by the utility of this tool, developed by Anatomage and Stanford University's Division of Clinical Anatomy. Particularly for its ability to give anatomy students unprecedented access to special cases. Instead of waiting for a body with just the right kind of brain malformation or liver damage to come in, you can just call up the desired images from the computer and use them whenever you want.
As for the creepy: Well, for some reason it's just a little more disturbing to see a perfectly healthy naked lady sprawled out on the anatomy table, as opposed to old, wrinkly naked people or people who have clearly recently been in poor health. (Also, potentially NSFW, natch.)
Canadian artist Howie Tsui redesigned a pinball machine to turn it into a crude simulation of a musket-ball rattling around a soldier's guts for a War of 1812-themed exhibition currently running at the Agnes Etherington Arts Centre at Queens University in Kingston. It's meant to demonstrate the way that repetition and concentration can inure you to the horrors of war:
The first part of his exhibition is a re-themed pinball machine, which now, having been Tsui-ed, is called Musketball! Tsui repainted the front glass panel and it now shows a British soldier reeling back as his guts explode from a musket shot (no rolling around inside for this one). The playing surface is painted with organs, tissue and bone, with the words “mangled viscera” at midfield. It would all be tame in a modern shooter video game, but it’s shockingly graphic on a vintage board.
I step up to the game and fire my first ball, which gets back in the gutter faster than I thought possible. I fire the second ball — which I note are gold, not silver, to which Tsui says, “I kind of blinged it up a little bit.” This ball stays in play just long enough to hit a few bumpers and set off sound effects of rifle shots and artillery blasts. I fire my remaining three balls, and my final score is slightly less than one-tenth of Tsui’s high score. “It’s your first time playing. I had to do a lot of testing,” Tsui says, showing he’s also talented in the art of diplomacy.
“After a while,” he says, “you sort of get hooked on the game, and the whole idea for me is that it distances the player from the idea of violence.”

This 1919 French laxative ad promises that it will set lose a cadre of tiny sewage workers who will personally scour your colon of impacted poop.
Dr Shankar’s Brain Museum in Bangalore is shelf upon shelf of largely unlabelled brains in jars, along with various other bits of anatomical pickle (human and otherwise). Andy Deemer took a visit and provides some lovely snapshots.
I’m not sure that I’d call Dr Shankar’s Brain Museum a museum. There were no explanations, no details, no citations or learning. Just six hundred brains in an otherwise empty room.
On reflection, perhaps “Collection” would be a better word. A fantastic collection of diseased and healthy brains, sandwiched between a Brain Bank and the Hospital Canteen.
Two dozen purple slides showed something. Ten or so brains were marked by a shared label: Intracerebral Hemorrhage. Another row was marked Glioma. Arterial Stroke. Schwannoma. Schizophrenia.
Evan Doney, a grad student in Matthew Leevy's biological imaging facility at the University of Notre Dame, has published a method for creating a 3D printed, life-size, accurate skeleton of a living animal by converting a CT scan of the animal to a printable file. They produced a detailed HOWTO as well, which, unfortunately, is paywalled.
The idea to print skeletons from CT scans came from Evan Doney, an engineering student working in the lab of Matthew Leevy, who runs the biological imaging facility at the University of Notre Dame. ”At first I didn’t really know what the killer app would be, I just knew it would be really cool,” Leevy said. But he began to see new possibilities after striking up a conversation with an ear, nose, and throat specialist during an office visit for a sinus problem. “I actually got out my computer and showed him some slides, and by the end of it we were collaborating.”
Doney used several freeware programs to convert data from CT scans into a format that could be read by a 3-D printer. As a proof of principle, he and colleagues printed a rat skeleton in white plastic and printed a removable set of lungs in green or purple. They also printed out a rabbit skull.
I have a 3D print of my femur in bronze and stainless steel, courtesy of my wife and her raid on my MRIs. Sounds like you get an even better shapefile from a CT scan, if you don't mind receiving the radiation equivalent of 800 X-rays.
