New Proposal to Define the Fascial System.

At the beginning of the third millennium, we still do not have a definition of 'fascia' recognized as valid by every researcher. This article attempts to give a new definition of the fascial system, including the epidermis, by comparing the mechanical-metabolic characteristics of the connective tissue and the skin. In fact, according to the latest classification deriving from the Fascia Nomenclature Committee, the outer skin layer is not considered as part of the fascial continuum.
