    Transcript
    In this lecture we are going to look at the posterior abdominal wall. So we will look at the boundaries of the posterior abdominal wall from the lumbar vertebrae and the iliac crest. And we will look at the muscles that form the diaphragm, psoas muscles, quadratus lumborum, and the iliacus. We will look at the vasculature that’s running up and down the posterior abdominal wall, primarily, the abdominal aorta in the inferior vena cava. And then we will look at the nerves that are positioned on the posterior abdominal wall specifically the somatic nerves. We not going to concentrate on the autonomic nerves just yet we will look at those towards the end of the course. So the posterior abdominal wall is a muscular region that sits either side of the 5 lumbar vertebrae. It supports the retroperitoneal organs like kidneys, pancreas and duodenum. But it also contains numerous important neurovascular structures like the abdominal aorta and the IVC like I have suggested. So let's have a look at the boundaries of the posterior abdominal wall. And here we have just got the schematic that's looking at the skeleton of the posterior abdominal wall. And you can see we have got the lumbar vertebrae here 5, 4, 3, 2, 1. The 5 lumbar vertebrae that form the posterior abdominal wall. We can see we have got the 12th rib running around in this direction. And we have got the iliac crest and we have got the pelvic brim around in this direction. So the posterior abdominal wall is really this region which we can see here. We can see it clearly in this posterior view as the posterior abdominal wall really being in this kind of area here. So we can see we have some details. We have got...
