• \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.\Structure of cavity and/or content of pelvis (body structure)\This structure comprises the space and content within the boundaries of the cavity of the true pelvis (also known as the cavity of the minor or lesser pelvis) 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-pelvic structure is bounded by, but excludes the following 'wall' structures: superiorly the superior pelvic aperture; inferiorly the inferior aperture of true pelvis and pelvic diaphragm; and laterally the pelvic wall. Note, the structures that form the boundaries are excluded. The content includes the urinary bladder, sigmoid colon (although it is acknowledged that this is mobile and sits in a variable location), rectum, anal canal, pelvic segment of ureter and the retropubic and presacral space; the female pelvis also includes the ovaries, fallopian tubes, uterus, vagina, female urethra, soft tissues including the broad ligament and the retrouterine pouch of Douglas.; the male true pelvis also includes the prostate, male urethra, seminal vesicles, soft tissues including the pubovesical and puboprostatic ligaments and the retrovesical space.\Structure of serous membrane of pelvic peritoneum\Pelvic peritoneal pouch

• \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).\Serous sac structure\Peritoneal sac structure\Structure of serous membrane of peritoneum (body structure)\Structure of serous membrane of pelvic peritoneum\Pelvic peritoneal pouch

• \Body region structure\Body part structure\Trunk structure (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.\Structure of cavity and/or content of pelvis (body structure)\This structure comprises the space and content within the boundaries of the cavity of the true pelvis (also known as the cavity of the minor or lesser pelvis) 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-pelvic structure is bounded by, but excludes the following 'wall' structures: superiorly the superior pelvic aperture; inferiorly the inferior aperture of true pelvis and pelvic diaphragm; and laterally the pelvic wall. Note, the structures that form the boundaries are excluded. The content includes the urinary bladder, sigmoid colon (although it is acknowledged that this is mobile and sits in a variable location), rectum, anal canal, pelvic segment of ureter and the retropubic and presacral space; the female pelvis also includes the ovaries, fallopian tubes, uterus, vagina, female urethra, soft tissues including the broad ligament and the retrouterine pouch of Douglas.; the male true pelvis also includes the prostate, male urethra, seminal vesicles, soft tissues including the pubovesical and puboprostatic ligaments and the retrovesical space.\Structure of serous membrane of pelvic peritoneum\Pelvic peritoneal pouch
