This concept describes the layered structure of the anterolateral abdominal wall, from superficial skin through fascial and muscular planes to the peritoneal cavity, as a sequential anatomical arrangement. It belongs to human gross anatomy, specifically abdominal wall anatomy, defining each layer's identity and relative depth: superficial fascia (Camper's fatty layer and Scarpa's membranous layer), the three flat muscle layers (external abdominal oblique, internal abdominal oblique, transversus abdominis), and the deep layers (transversalis fascia, extraperitoneal layer, parietal peritoneum). The organizing principle is that these layers are consistently ordered from superficial to deep and each has a distinct histological/fascial identity, culminating in the parietal peritoneum as the boundary of the peritoneal cavity containing the abdominal viscera.
