• \Body wall structure\This structure surrounds the abdominopelvic cavity and has two regional parts: the wall of abdominal proper segment of trunk and the pelvic wall, but excludes the pelvic floor and the thoracic diaphragm.\This structure is comprised of the anterior and posterior abdominal wall.\The anterior abdominal wall constitutes a hexagonal area defined superiorly by the costal margins and xiphoid process; and inferiorly by the iliac crests, inguinal ligament, pubis and pubic symphysis. The wall extends posteriorly and incorporates the lateral aspect of the wall until the junction with the posterior abdominal wall approximately at the mid-axillary line. The wall is covered externally by skin and subcutaneous tissue: beneath this lies the superficial fascia (between the dermis and the muscles), which is conventionally divided into a superficial fatty layer (Camper's fascia) and a deep membranous layer (Scarpa's fascia); deep fascia; the rectus abdominis, pyramidalis, external oblique, internal oblique and transversus abdominis; and the extraperitoneal tissue and the parietal peritoneum. These tissues also form the umbilicus and the inguinal canal, which connects the abdominal cavity to the scrotum in males and the labia majora in females.\Structure of lateral half of anterior abdominal wall\Linea semilunaris

The volume is bounded by, but excludes: superiorly the thoracic diaphragm; inferiorly the pelvic diaphragm; and posteriorly the posterior wall of the abdomen proper: The pelvic component consists of the cavity of the true pelvis, which is bounded by, but excludes, the pelvic wall. Anteriorly this volume is bounded and includes the anterior abdominal (including the lateral abdominal wall).\Structure of lateral half of abdomen lateral to midsagittal plane\Structure of lateral half of anterior abdominal wall\Linea semilunaris
• \Body region structure\Body part structure\Trunk structure (body structure)\Structure of subregion of trunk (body structure)\This cross-sectional segment is bounded superiorly by a virtual horizontal plane at the level of the junction between T8 and T9 (and thus also includes part of the thoracic volume below this level); and inferiorly it extends to the perineum, including the volume of the true and false pelvic cavities and part but not necessarily the entire external genitalia.

This space and content is bounded by, but excludes: superiorly the thoracic diaphragm; inferiorly the superior pelvic aperture; and posteriorly the posterior wall of abdomen proper. Anteriorly this volume is bounded and includes the anterior abdominal (including the lateral abdominal wall).\The anterior abdominal wall constitutes a hexagonal area defined superiorly by the costal margins and xiphoid process; and inferiorly by the iliac crests, inguinal ligament, pubis and pubic symphysis. The wall extends posteriorly and incorporates the lateral aspect of the wall until the junction with the posterior abdominal wall approximately at the mid-axillary line. The wall is covered externally by skin and subcutaneous tissue: beneath this lies the superficial fascia (between the dermis and the muscles), which is conventionally divided into a superficial fatty layer (Camper's fascia) and a deep membranous layer (Scarpa's fascia); deep fascia; the rectus abdominis, pyramidalis, external oblique, internal oblique and transversus abdominis; and the extraperitoneal tissue and the parietal peritoneum. These tissues also form the umbilicus and the inguinal canal, which connects the abdominal cavity to the scrotum in males and the labia majora in females.\Structure of lateral half of anterior abdominal wall\Linea semilunaris
