Okay now we can look at the holes on the inside here so again form and make them the big hole. Our jugular frame is right here. Internal auditory meadis is just above that. On the other side of the petriest portion we can see the lasernum 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 crotic canal coming through. If I stick it through on this side you can see it polled right there. Okay. Your oval from an oval. The rotundum is this smaller rounded hole right here. Our optic canals are just under the lesser wings right here.
