Curiously vampiric teeth of untreated syphilis sufferers


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).

How to: Sex your crocodile

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!

Anatomical sweatshirt you can't have


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.

Bar needs new human toe after mystery man consumes their mummified garnish


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.

Anatomical maquettes of fanciful creatures


(Ganesha 2011)

Sculptor Masao Kinoshita's work comes in a variety of forms, but what really tweaks my amygdala are the anatomical maquettes of fanciful creatures. I mean, PHWOAR. SHUT UP AND TAKE MY MONEY.

Molars colonized by ambitious antiquarian architecture


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."

Internal anatomy of the clitoris


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.

Science of penis-barb shaving


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.

Anatomy tees redux


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.

Virtual dissection table is fascinating, useful, and just a little creepy

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.)

Duck penises: The saga continues

As we all know by now, ducks have penises. Rather epic penises, in fact. Chickens, though, are penis-less. In fact, most birds don't have them. In an important update in duck sex news, Ed Yong follows the work of several scientists who are trying to better understand how genitals evolve and why they differ so much between species and genuses. Bonus new fact: A dissected goose penis looks surprisingly like a less-colorful Man-O-War jellyfish.
