What half a horse head looks like

Hemisected horse head

Continuing the recent theme. We’re not giving this a “Things to Make and Do” header because the spirit of that category is to showcase anatomical preparations that average people could do in the comfort of their own homes and gardens (provided they can get hold of dead wallabies, bear skulls, etc.), and freezing and band-sawing a horse is probably outside that envelope for almost everyone (I hadn’t though of that when I posted the gator!).

In the spirit of MYDHHH:

Hemisected horse head with scale

This ain’t mine, it’s a teaching specimen from our vet school, which has a no-kill policy. All of the animal cadavers used in the anatomy labs are donated by the owners at the ends of the animals’ natural lives. So no animals were harmed in the making of this science.

But I wish it was mine. And as long as I’m dreaming, I’d like a pony. Anyone want to go halvesies?

    What a beautiful piece of artwork that cleaned-up version is, on its plain white background.

    The nasal cavity is as big as the mouth!

    I don’t understand what’s going on above the larynx. Is that a huge pharynx with bits of tissue dangling into it?

    I think so. It probably includes the guttural pouch, which is a weird diverticulum. See Darren’s Tet Zoo post for more.

  6. […] Another difficulty with this interpretation of horizontality is that it can make the neural canal jagged. Consider a sequence of vertebrae oriented as in part A, all at the same height: the neural canal would rise upwards along the length of each vertebra, before plunging down again on transitioning from the front of one to the back of the next. This is not something we would expect to see in a living animal: see for example the straight line of the neural canal in our hemisected horse head(*). […]
