O.K., one last bone. This is the busiest bone in skull-biz, the sphenoid. You're looking down on top of it. The curved portion facing the top of the screen backs up your eyes. The two big projections in front of that help hold up your nose. The diagonal flat surfaces off to the sides form parts of your temples. The surface you're looking at helps hold up your brain. And, last, but definitely not least, right in the middle, along the bottom edge, is the sella turcica (a.k.a. the "Turkish saddle"), which is where your pituitary gland rides. And we don't even want to get into what a busy bit of brain that is.

Especially not with 5 days of holiday, right? Let loose the hounds!
