For your information... Layers of the Abdominal Wall

Here are the layers of the anterior abdominal wall from superficial to deep:

• Skin
• Fascia
• Camper's - superficial fatty layer
• Scarpa's - deep fibrous layer
• Muscle
• Rectus abdominis
• External Oblique
• Internal Oblique
• Transversus abdominis
• Transversalis Fascia
• Peritoneum

The only change from this is below the Arcuate Line when the Internal Oblique and Transversus Abdominis aponeuroses merge and pass superficial to the Rectus muscles. This means that the Rectus Abdominis rests directly on the Transversalis fascia below the Arcuate line.
