Transverse Section - Pelvis
You selected: abdominal wall musclesAt this level little can be seen of the muscles of the anterior abdominal wall, aside from the centrally located rectus abdominus Of the three remaining muscles, the external oblique muscle is the most external of the three. It's muscle fibers run perpendicularly to those of the underlying internal oblique muscle. These two muscles help compress the abodomen when straining, and flex the torso when twisting or bending from side to side. The fibers of the third muscle, the transversus abdominus run horizontally. Sit-ups exercise all three muscles.
