It's amazing how many places those little zingers hit, isn't it?
Thanks for the diagram. What I've learned over the last year and a half is that there are little branches from the TN nerve that go to each of the teeth -- that's why a lot of us experience 'toothache' like pain. And the diagram shows that it connects into the nose area -- that's where I had my first electric zap.
If you click on the diagram, it will enlarge it so you can see things more accurately....
