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!
