I'm curious about why the arcuate line of the posterior wall of the rectus sheath even exists. Why doesn't the aponeurosis of the tranversus abdominis muscle continue deep to the rectus abdominis muscle for the entire length of the rectus sheath? Is there an embryological basis for the arcuate line (i.e. what happens during development that causes the formation of the arcuate line)? Thanks for your time!
