Title: abdominal cavity Post by: faraday Jr on Feb 1, 2011 describe the lining of the abdominal cavity?
I'm not sure what they mean by "the Lining" do they mean the subdivision of the abdominal cavity? Title: Re: abdominal cavity Post by: star on Feb 1, 2011 Hey faraday Jr.
To my understanding, it's the outer most layer of the abdominal cavity itself (not the organs), which technically is called the peritoneum. Although the peritoneum forms one continuous sheet, two types or layers of peritoneum and a potential space between these two layers are referenced: - The outer layer, called the parietal peritoneum, is attached to the abdominal wall. - The inner layer, the visceral peritoneum, is wrapped around the internal organs that are located inside the intraperitoneal cavity. - The potential space between these two layers is the peritoneal cavity; it is filled with a small amount (about 50 ml) of slippery serous fluid that allows the two layers to slide freely over each other. The term mesentery is often used to refer to a double layer of visceral peritoneum. There are often blood vessels, nerves, and other structures between these layers. The space between these two layers is technically outside of the peritoneal sac, and thus not in the peritoneal cavity. |
