Each discipline operates from different rules and definitions. A system can be defined as "a set of things working together as parts of a mechanism or an interconnecting network; a complex whole".

The Fascia Nomenclature Committee, a group of international experts from different backgrounds clearly says yes in their current definitions, but anatomist disagree. Articles that may help you think more about this after you listen in to this episode are below.
