Anatomy Question: Ridges on Forehead

I know this isn't hair loss question, but I have no idea where to get the answer.  Let me know if there is a better forum.

I've noticed on either side of my forehead that there are bony ridges protruding from my skull.  I was wondering if there's a term for this.  If you want a picture, here is a picture of an actor in the movie Unforgiven where I noticed the same thing: http://img11.imageshack.us/img11/494/forehead.png

Any help would be appreciated.  Thanks.

It's just bone structure.  Potentially very attractive bone structure, actually.  Ed Harris has it.  You don't see it much lately because it can disappear with obesity.
