I don't have a name for them. I use them for Path / Owner highlight. 

Where are things located, you have something highlighted, that belongs / is owned in that linked component.

Might help....

I know that Autodesk has an official name for it. It's got to be sitting somewhere in the product documentation.

"Breadcrumbs" is what they are called.
