Mesoperitoneal Organs and Peritoneum Quiz and Flashcards

Study Notes

The peritoneum is a serous membrane that lines the inside of the abdominal wall and surrounds organs in the abdominal cavity.
It consists of two main parts: the parietal peritoneum, which lines the internal surface of the abdominal and pelvic wall, and the visceral peritoneum, which lines the walls of the organs forming a wet and serous coat.
Between the parietal and visceral peritoneum lies the peritoneal cavity, containing serous fluid produced by these membranes.
The visceral peritoneum covers organs in three ways: intraperitoneal organs are completely invested in the visceral peritoneum, mesoperitoneal organs are partly invested from three sides, and retroperitoneal organs are covered from only one side.
Ligaments like the falciform ligament and lesser omentum connect the parietal and visceral peritoneum, providing structural support to the abdominal organs.
The lesser omentum consists of two ligaments connecting the liver to the stomach and duodenum, while the greater omentum consists of three ligaments connecting the stomach to the diaphragm, spleen, and transverse colon.
The greater omentum is characterized by a double-layered fold that surrounds the transverse colon, providing additional protection to the abdominal organs.- The peritoneum is a membrane that covers the organs in the abdominal cavity.
The mesentery is a part of the peritoneum that connects the intestines to the posterior abdominal wall.
The mesentery surrounds the intestines and forms a pathway for vascular supply.
The peritoneal cavity has three levels: upper, middle, and lower.
The upper level has recesses called the subphrenic recess, subhepatic recess, and omental bursa.
The omental bursa is also known as the lesser sac and is separated from the greater sac by the omental foramen.
The middle level of the peritoneal cavity contains recesses located behind various organs, such as the duodenum and caecum.
The lower level of the peritoneal cavity has pouches in females called the rectouterine pouch and vesicouterine pouch, and in males called the rectovesical pouch.
