I was talking about the arcuate line of the anterior abdominal wall this week, and as I worked so hard to understand and explain it I thought I'd explain it again here. Efficiency of effort and all that.
The arcuate line describes the change in the posterior lamina of the rectus abdominis sheath.
We'll look at the muscles of the abdominal wall, how most of them become fibrous aponeurosis sheets that surround the rectus abdominis muscle, and how that is different superior and inferior to the arcuate line.
