External Oblique. The largest and most superficial flat muscle in the abdominal wall. Its fibres run inferomedially. As the fibres approach the mid-line, they form an aponeurosis (a broad flat tendon). In the mid-line, the aponeuroses of all the flat muscles become entwined, forming the linea alba.his is a long, paired muscle, found either side of the midline in the abdominal wall.
