• \Anatomical structure which has as its parts a heterogeneous collection of organs, organ parts, cells, cell parts or body part subdivisions that are adjacent to, or continuous with one another; does not constitute a cell part, cell, tissue, organ, or body part subdivision.\Structure of anatomical compartment (body structure)\Structure of body cavity and/or content\...

• \This structure comprises the space and content within the boundaries of the abdominopelvic cavity but excludes the walls that define and enclose the space. Previously SNOMED CT used the word 'compartment' to describe structures comprising the cavity and content but FMA has used the same word to include cavity, content and wall. As a consequence, the preferred notation is intra-abdominopelvic structure as this more clearly excludes the 'wall' structures. The intra-abdominopelvic structure is bounded by, but excludes the following 'wall' structures: superiorly the thoracic diaphragm; inferiorly the pelvic diaphragm; anteriorly the anterior abdominal wall (including the lateral abdominal wall); and posteriorly the wall of the abdominal proper segment of trunk. The pelvic component consists of the cavity and content of the true pelvis, which is bounded by the pelvic wall. Note, the structures that form the boundaries are excluded.\Peritoneal sac structure\Peritoneal ligament\Structure of false ligament of urinary bladder\Structure of lateral umbilical ligaments
• \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.\...
