It arises from the anterior surface of the lateral mass of the atlas, and from the root of its transverse process, and passing obliquely upward and medialward, is inserted into the inferior surface of the basilar part of the occipital bone immediately in front of the foramen magnum.
action: aids in flexion of the head and the neck; nerve supply: C1, C2.[1]

gollark: So I decided to look at the website on a device which could actually render the sculpture thing, and looking at the FAQ, this seems... odd...:> Each unique seed is stored immutably on the blockchain, and while seeds are case-sensitive, your seed (and therefore, your sculpture) cannot be duplicated by anyone.... *what* does case sensitivity have to do with anything? How can it "not be duplicated"?
gollark: There's this nice one I use for wallpapers: https://github.com/TomSmeets/FractalArt/
gollark: Calling NFTs a form of art themselves, and not the artistic thing they happen to be tied to, seems like calling the fiat currency you might buy artwork with also art.
gollark: Anyway, while it does seem like a cool generative art-type thing (the viewer runs very slowly on my phone so it's hard to tell) I don't think the NFT bit is intrinsic to it at all, or relevant to it except as a somewhat weird way to have it pay for itself.
gollark: 5 million LoC implies you wrote 120000 a day, which seems implausible. And/or would suggest you did waaaaay too much work.
