Scientific Illustration

Here’s a pretty quick sketch I recently did comparing the lynganeal nerve in humans and giraffes. I have a few more sketches to take care of and then I’ll hopefully have some Mandarin Ducks in progress this weekend. :)

This is for any of you who were interested in some of the info in my last post: here.

I’ve loved/lived around horses my entire life, and actually already knew some of this. I wasn’t quite sure what each bone was called, but I knew basically where they were located on each creature.

Quite a few of the bones are the same, such as the tibia, humerus, and femur. Others have different names for the same basic part, like the knee of a horse and the wrist of a human.

So basically, on a horse, the “hands and fingers” are from the knee, down. They’re just very….extended. Think of the entire hoof as being the fingernails.

On a pony, the tibia and fibula have to be shorter than on a real horse, but they’re still there, connecting to the hock, which is that “pointy” part on the hind legs.
