Fasciae are layers of connective tissue, mainly collagen, situated under the skin, which closes, supports, and separates muscles and other structures. Fasciae are grouped by their anatomical location, layer (as visceral fascia, superficial fascia, and deep fascia), or by their functions. Fasciae reduces friction and provide an adjustable covering for nerves and blood vessels as they move through muscles.
