I always see representations of the solar system with the planets existing on the same plane. If that is the case, what is "above" and "below" our solar system?

Sorry if my terminology is rough, but I have always thought of space as infinite, yet I only really see flat diagrams representing the solar system and in some cases, the galaxy. But with the infinite nature of space, if there is so much stretched out before us, would there also be as much above and below us?

In the solar system, all of the planets are on the same plane, but there are lots of smaller objects which have orbits which are at angles to the plane of the planets.

As for the galaxy, it is also roughly flat, and has a diameter about 100 times larger than it's thickness. Within the galaxy, the stars have planetary systems which are aligned randomly at all different angles to the plane of the galaxy.
