• \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.\Retroperitoneal compartment structure (body structure)\Structure of retroperitoneal region, excluding major organs\Structure of iliopsoas muscle\Structure of psoas muscle\Structure of psoas minor muscle (body structure)
• \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 posterior abdominal wall consists of the posterior abdominal wall musculature including the quadratus lumborum, psoas major and psoas minor and crus of lumbar part of diaphragm; the lumbar vertebrae bodies and transverse processes; the posterior part of abdominal peritoneum; and the abdominal wall including the transversus abdominus, internal and external oblique muscles posterior to the mid-axillary line. This definition is sometimes referred to as the posterior wall of abdomen proper as it excludes the more superficial layers of muscle and skin of the back: the middle layer of the thoracolumbar fascia (medially attached to the transverse process of the vertebra), and the lateral raphae constitute the posterior boundary of the posterior wall of abdomen and separate it from more caudal structures which are part of the lumbar region of back.\Structure of psoas muscle\Structure of psoas minor muscle (body structure)
• \An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Structure of striated muscle and/or smooth muscle\...

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.
