This anatomical abdominal region division is used to recognize the location of the abdomen organs and to diagnose abdominal pain. Deeper fibers pass behind the rectus abdominis, attaching to the posterior pubic crest to create a triangular lamella known as the "adminiculum lineae albae." (See the image above. Each muscle is divided along its course by 3 or 4 transverse fibrous bands known as tendinous intersections, which essentially divide the muscle into a series of interconnected muscles. This layer can vary in thickness from less than 1 cm to greater than 15 cm, depending on a person's body habitus.
