 Okay, now we can look at the holes on the inside here, so again, Forman magnum, the big hole. Our jugular foramen is right here, internal auditory meatus, it's just above that. On the other side of the petrus portion, we can see the lecernum, this hole right here, and kind of coming into it from the side, I can stick my probe into that hole there. That's the karate canal coming through. If I stick it through on this side, you can see it poking out right there. Your oval, Forman oval, the rotundum is the smaller rounded hole right here. Our optic canals are just under the lesser wings right here.
