Parietalperitoneum
Parietal peritoneum, commonly referred to as the parietal peritoneum, is the serous membrane lining the internal surface of the abdominal and pelvic walls and the inferior surface of the diaphragm. It forms the outer layer of the peritoneal cavity and is separated from the underlying organs by a thin film of peritoneal fluid. The visceral peritoneum covers most intraperitoneal organs, and the two layers are continuous at the reflection points that form mesenteries, ligaments, and omenta.
Structure and relations: The parietal peritoneum is a simple squamous epithelium (mesothelium) supported by connective tissue.
Innervation and sensation: The parietal peritoneum has somatic sensory innervation, typically via the nerves supplying the
Vascular supply and drainage: Blood supply mirrors that of the adjacent body wall, from intercostal, lumbar,
Function: The parietal peritoneum provides a protective lining, participates in the production of peritoneal fluid that
