From Wikipedia, the free encyclopedia. The external oblique muscle (of the abdomen) (also external abdominal oblique muscle) is the largest and the most superficial (outermost) of the three flat muscles of the lateral anterior abdomen.
Acting alone, the external oblique can flex the trunk, side bend the torso toward the same side (i.e., the side of the contracting muscle), and rotate the trunk toward the opposite side. The internal oblique originates from the thoracolumbar fascia, the inguinal ligament, and the anterior iliac crest.
