Longus capitis muscle

The longus capitis muscle (Latin for long muscle of the head, alternatively rectus capitis anticus major), is broad and thick above, narrow below, and arises by four tendinous slips, from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebræ, and ascends, converging toward its fellow of the opposite side, to be inserted into the inferior surface of the basilar part of the occipital bone.

gollark: It is entirely possible that the money/time tradeoff is worse for copy protection than actually adding features.
gollark: If a random person can do it so can probably other people.
gollark: Because someone will just break it *anyway*, it'll be copied, and you'll have done more work and probably irritated paying users a bit with licensing.
gollark: Which WON'T WORK WELL.
