Now that we’ve looked at all the muscles that form the walls of the abdominal cavity, we’ll take a look inside the cavity itself. To do that we’ll look at a dissection in which the abdominal organs, and the left half of the anterior abdominal wall have been removed. Here’s the serous membrane that lines the abdominal cavity, the parietal peritoneum. We’ll see it in more detail in volume six.
Beneath the peritoneum there’s a continuous layer of loose connective tissue, here as we’ve seen it’s called the iliacus fascia. Here on the inside of the anterior abdominal wall it’s called the transversalis fascia
