Internal occipital crest
In the occipital bone, the lower division of the cruciate eminence is prominent, and is named the internal occipital crest; it bifurcates near the foramen magnum and gives attachment to the falx cerebelli; in the attached margin of this falx is the occipital sinus, which is sometimes duplicated.

In the upper part of the internal occipital crest, a small depression is sometimes distinguishable; it is termed the vermian fossa since it is occupied by part of the cerebellar vermis of the cerebellum.

gollark: As I've said previously, the graph of technology level to infrastructure required to keep that going is probably quite inverted-U-shaped, and commune stuff can probably only work at the lower ends.
gollark: ... impractical.
gollark: There are also people with *too much* food, which is a less bad problem than too little.
