Your core is built from layers of muscle — each with a distinct function. From outer to inner, the lateral abdominal wall consists of: 🔸 External oblique 🔸 Internal oblique 🔸 Transversus abdominis At the front, the rectus abdominis ("six-pack") runs vertically. Beneath everything: the transversalis fascia and peritoneum. This 3D exploded view animation reveals the layered anatomy of the abdominal wall — crucial for posture, movement, and protecting internal organs. Based on SciePro’s 3D anato

External abdominal oblique is a paired muscle located on the lateral sides of the abdominal wall. Along with internal abdominal oblique and transversus abdominis, it comprises the lateral abdominal muscles. In a broader picture, these muscles make up the anterolateral abdominal wall together with two anterior abdominal muscles; the rectus abdominis and pyramidalis. Origin and insertion External abdominal oblique muscle originates from the external surfaces of ribs 5-12. The attaching fibers inte
