New Proposal to Define the Fascial System.

Area of Science:

• Anatomy
• Histology
• Biophysics

Background:

• The definition of fascia remains inconsistent among researchers.
• Current classifications exclude the epidermis from the fascial continuum.
• There is a need to consider functional properties alongside tissue structure.

Purpose of the Study:

• To propose a new definition of the fascial system that includes the epidermis.
• To highlight the importance of mechanical-metabolic characteristics in defining fascial tissue.
• To challenge traditional structural classifications of fascia.

Main Methods:

• Comparative analysis of mechanical-metabolic characteristics of connective tissue and skin.
• Review of current fascia nomenclature and classifications.
• Discussion on embryonic origins and tissue stratification.

Main Results:

• The epidermis shares functional characteristics with fascial tissues.
• Structural definitions may not accurately represent in vivo tissue interactions.
• A functional definition integrating the epidermis is proposed.

Conclusions:

• The fascial system should be redefined to include the epidermis based on functional properties.
• Functional characteristics are crucial for understanding tissue continuum.
• The proposed definition serves as a starting point for further research into fascial anatomy.
