@oristarA,
Yes the "connecting loops" are what is being refered to as "slim"
At the top of the orange spiral is one of the connecting "loops". It connects the orange spiral to the ?cell? ( i dont know what that is).
A loop does not necessarily have to be a full circle, as long as it curves somewhat and connects two points together it could be described as a connecting loop.
additional usage
Keeping someone "in the loop" means keeeping someon informed and up to date with current information.
Loopy means mad, crazy, mentally deficcient. silly.
Oristar is a bit loopy. (Oristar is silly/ crazy /mentally unstable).
