What are the different derivatives of the peritoneum?
Terms in this set (6)
- mesentery proper. supports the small intestine.
- mesocolon. supports the large intestine.
- falciform ligament. attaches the liver to the anterior abdominal wall and to the diaphragm.
- greater omentum.
- lesser omentum.
- mesoappendix.
What are the four types of peritoneum?
Both types are made up of simple squamous epithelial cells called mesothelium.
- Parietal Peritoneum. The parietal peritoneum lines the internal surface of the abdominopelvic wall.
- Visceral Peritoneum. The visceral peritoneum invaginates to cover the majority of the abdominal viscera.
- Peritoneal Cavity.
What are the 5 major folds of the peritoneum?
The peritoneum folds into five key components (see below): the greater omentum, the lesser omentum, the falciform ligament, the small bowel mesentery, and the mesocolon. The folds extend over the viscera and also line the abdominal cavity.
What is the function of peritoneum?
The peritoneum serves to support the organs of the abdomen and acts as a conduit for the passage of nerves, blood vessels, and lymphatics.
What kind of membrane is the peritoneum made of?
Peritoneum, Mesentery, and Omentum The peritoneum is thin membrane that lines the abdominal and pelvic cavities, and covers most abdominal viscera. It is composed of layer of mesothelium supported by a thin layer of connective tissue. Although ultimately one continuous sheet, two types of peritoneum are referenced:
Where does the lesser omentum and parietal peritoneum form?
The lesser omentum arises from the lesser curvature of the stomach and extends to the liver. The greater omentum is given off from the greater curvature of the stomach, forms a large sheet that lies over the intestines, then converges into parietal peritoneum.
How does the peritoneum support the abdominopelvic organs?
The peritoneum functions to support and protect abdominopelvic organs. This article will discuss the anatomy of the peritoneum, including key related topics; peritoneal cavity, omenta, mesentery, ligaments, and peritoneal relations.
What happens to the parietal and visceral peritoneum?
This can result in abnormal attachments between the visceral peritoneum of adjacent organs or between visceral and parietal peritoneum. Such adhesions can result in pain and complications such as volvulus, when the intestine becomes twisted around an adhesion resulting in a bowel obstruction.
