• \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\...

• \Mesenteric plexus\An autonomic plexus that branches from the aortic plexus, that sends nerves to descending colon, sigmoid, and rectum along the path of the inferior mesenteric artery\An autonomic plexus that branches from the inferior mesenteric plexus; accompanies superior rectal artery to rectum.
• \Abdominal aortic plexus structure\An autonomic plexus that branches from the aortic plexus, that sends nerves to descending colon, sigmoid, and rectum along the path of the inferior mesenteric artery\An autonomic plexus that branches from the inferior mesenteric plexus; accompanies superior rectal artery to rectum.
• \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.\Rectal plexus\An autonomic plexus that branches from the inferior mesenteric plexus; accompanies superior rectal artery to rectum.

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.\Rectal plexus\An autonomic plexus that branches from the inferior mesenteric plexus; accompanies superior rectal artery to rectum.
• \Body region structure\Body part structure\Trunk structure (body structure)\Structure of subregion of trunk (body structure)\This segment relates to the volume of the trunk that is bounded by and includes: superiorly thoracic diaphragm and inferiorly the perineum and external genitalia. 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 segment relates to the volume of the trunk that is bounded superiorly by and includes: superiorly the boundary of the false pelvis, which is an artificial plane from the symphysis pubis to the superior iliac crests (in front it is incomplete, presenting a wide interval between the anterior borders of the ilia); and inferiorly the perineum and external genitalia. 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 volume of the true and false pelvic cavities including the bony pelvis and pelvic wall and the entire perineum and external genitalia. Note, the entire bony pelvis is included within the pelvic segment (but is excluded from the abdomen proper segment of trunk); however the pelvic segment of trunk and the abdomen proper segment of trunk both include the volume of the false pelvis.\This structure, also termed the pelvic region, includes the wall, cavity and content of both the true and false pelvis; it consequently incorporates the entire bony pelvis; and inferiorly it is bounded and includes the pelvic diaphragm. The structure incorporates the complete pelvic wall; sacrococcygeal region (including the overlying skin and subcutaneous tissue); the contents of the false pelvic cavity; but in contrast to the 'pelvic segment of trunk' excludes the perineum, external genitalia.\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.\Rectal plexus\An autonomic plexus that branches from the inferior mesenteric plexus; accompanies superior rectal artery to rectum.
