The linea semilunaris is a curved tendinous line placed one on either side of the rectus abdominis.
Each corresponds with the lateral border of the rectus abdominis, extends from the cartilage of the ninth rib to the pubic tubercle, and is formed by the aponeurosis of the internal oblique at its line of division to enclose the rectus, reinforced anteriorly by the external oblique and posteriorly by the transversus abdominis above the arcuate line (aka Linea semicircularis)
