Study Notes
Retroperitoneal Viscera
- Retroperitoneal viscera develop from the beginning as paired structures.
- Key organs include:
- Suprarenal glands
- Kidneys
- Ureters
Secondarily Retroperitoneal Viscera
- These viscera initially develop intra-abdominally and later become retroperitoneal.
- Notable unpaired organs are:
- Duodenum
- Pancreas
- Ascending colon
- Descending colon
Intraperitoneal Viscera
- Intraperitoneal viscera remain enclosed within peritoneum layers throughout development.
Omenta – Lesser Omentum
- The term "omenta" means 'apron' in Latin, specifically referring to the gastrohepatic ligament.
- Key attachments include:
- Lesser curvature of the stomach and proximal duodenum
- Visceral surface of the liver
- Important features:
- Acts as a pathway for neurovasculature
- Houses the portal triad
- Less variable in structure than the greater omentum
Peritoneal Ligaments - Liver
- Comprises several ligaments:
- Falciform ligament
- Anterior coronary ligament
- Left and right triangular ligaments
- Bare area of the liver
- The lesser omentum includes:
- Hepatogastric ligament
- Hepatoduodenal ligament
Peritoneum Overview
- The peritoneum is a continuous serous membrane lining the abdominal and pelvic viscera.
- Divided into two layers:
- Visceral peritoneum: covers the organs
- Parietal peritoneum: lines the abdominal wall
- Peritoneal connections consist of omenta, ligaments, and mesentery, facilitating neurovascular supply.
Peritoneal Cavity
- Refers to the potential space between the parietal and visceral peritoneum lined by peritoneal fluid.
- Contains the greater sac and lesser sac as its main divisions.
Mesentery
- The mesentery connects the jejunum and ileum to the posterior abdominal wall, extending to the appendix and possibly the cecum.
- Includes:
- Transverse mesocolon for the transverse colon
- Sigmoid mesocolon for the sigmoid colon
