The term "student bodies of a department or school" can be used to describe all students of a subject area (for example, all mechanical engineering students). Fortunately, within each student body there is a handful of committed people who are willing to represent this one towards the department and make their fellow students' studies as easy as possible.
The Departmental Student Council is basically your first contact point if problems arise concerning study matters.
You help determine the "official" members of your Departmental Student Council: at the university elections, among other things, it is determined who represents you in the TUM Student Council and who is an elected member of the Departmental Student Council. As a rule, however, all you have to do for participation is to ask! For many parts of the student body work, it doesn't matter if you are elected.
A special feature of the student bodies of the Weihenstephan Campus is their merger into a campus-wide Student Representation, the Council of Student Representatives / Rat der studentischen Vertretungen (RSTV).
