Superficial fascia is aka the subcutaneous layer. It is immediately deep to the skin. It is thin on the back of the hand. It is thick over the inferior abdominal wall. Between the inner and outer layers, arteries, veins, nerves, mammary glands and facial muscles are found.
Deep fascia is the most extensive of the three.
Subserous fascia is between the internal deep layer of the deep fascia and a serous membrane. It covers the external surfaces of viscera in the thoracic and abdominal cavities. Thus closes out the introductory portion of the muscles. Following this text are tables describing the number and name of the muscle that matches the illustrations, the origin of the muscle, the insertion of the muscle and the action perpetuated by the muscle by region, i.e., facial, anterior, posterior and perineal musculature. Figure 4 illustrates the musculature of the face.
