• \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.\...

The volume includes the entire transverse thickness of the body over the longitudinal extent between these upper (superior) and lower (inferior) boundaries including the overlying muscles, skin and subcutaneous tissue. The segment includes the abdominopelvic cavity, contents and wall including the posterior lumbar region, the volume of the true and false pelvic cavities including the bony pelvis and pelvic wall, the entire perineum and external genitalia including skin and subcutaneous tissue.\This is considered the most commonly used clinical variant of 'abdomen' and relates to the space and content within the abdominopelvic cavity plus the anterior and lateral abdominal wall. 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).\This is a clinical variant of 'abdomen' and relates to the 'abdomen proper' cavity which is defined as the abdominopelvic cavity and content, excluding the cavity and content of the true pelvis, plus the anterior and lateral abdominal wall (but excluding the posterior wall of the abdomen proper). 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\Structure of fascia of rectus abdominis muscle\Anterior rectus sheath
