Those are rings. this a nice example of galactic rings. the inner one is called an inner ring and the outer one is called an outer ring. Real original nomenclature Huh? Inner rings seem to be rather common but outer rings much less so. If the galaxy has a bar the inner ring very often seems to be attached to the ends of the bar.Some galaxies have an ellipsoidal area around the nucleus and bar (if it has one). I haven't found out what you would call this feature although it seems to me that it is related to the ring features. There is also a nuclear ring which I don't know what they look like. Hope this helps.
