Superficial thoracic and abdominal muscles, historical anatomical artwork. This ventral (front) view of a male torso shows the superficial (outermost) layer of muscles and tendons in the thorax and abdomen. The fan-shaped chest muscle is the pectoralis major, the shoulder muscle is the deltoideus. The abdominal muscle obliquus externus attaches to the white membranous aponeurosis covering the stomach area. The illustration is taken from the 19th century French textbook The Atlas of Human Anatomy and Surgery by J. M. Bourgery and N. H. Jacob.
