Explanation / Answer

A band of tough connective tissue in the midline of the anterior abdominal wall called the linea alba serves as a muscle attachment.   The rectus abdominis muscle spans from the ribs and the xiphoid process of the sternum to the pubic bones. The transversus abdominis forms the third layer (deepest layer) of the abdominal wall muscles. The action of the external oblique muscle is to compress the abdomen and flexion of the vertebral column. The action of the rectus abdominis is to compress the abdomen and flexion of the vertebral column. The iliocostalis, longissimus, and spinalis muscles togrther form the erector spinae.
