Well, what's "typical" varies from place to place.

Here's a diagram that seems OK to me.  The diagram is about
halfway down the page:

I'm sure there are also gazllions of wrong diagrams
out there, but I don't have time to go hunting for
them right now.

Perhaps you could ask a more specific question, with
pointers to some specific diagram(s).....
