To be clear:

1. There is only ever one region per buffer - not regions.

2. Wrt "hidden": The cursor is the point end of the region. It, at least, is 
always visible, never hidden. The region might not be highlighted, but its text 
is typically not hidden (invisible).

So it would be more accurate for you to speak of the region (singular) not 
being _highlighted_.
