816990003: Structure of cavity of false pelvis (body structure)

SNOMED CT Concept\Body structure (body structure)\Anatomical or acquired body structure (body structure)\Anatomical structure\...

\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.\...

\Structure of cavity and/or content of pelvis (body structure)\This cavity, is bounded by, but excludes: superiorly an artificial plane that extends from the symphysis pubis to the superior iliac crests; inferiorly the inferior aperture of true pelvis and pelvic diaphragm; and laterally the pelvic wall. The bony pelvis extends superiorly with the ilia, which anteriorly are incomplete, presenting a wide interval between the anterior borders of the ilia. The volume can be divided into the superior cavity of false pelvis and the inferior cavity of true pelvis. Note, the contents and structures that form the boundaries are excluded from the cavity.\The cavity, also known as the cavity of the major or greater pelvis, is bounded by, but excludes: superiorly an artificial plane that extends from the symphysis pubis to the superior iliac crests; and inferiorly the superior pelvic aperture. It is bounded on either side by the ilium; and in front it is incomplete, presenting a wide interval between the anterior borders of the ilia. It forms the inferior volume of the abdomen proper cavity, which includes a number of parts of structures of the intra-abdominal proper e.g. historically the cavity of false pelvis has been described as containing the 'iliac colon' which is a segment of the descending colon within the volume of the false pelvis. Note, the contents and structures that form the boundaries are excluded from the cavity.

It is bounded on either side by the ilium; and in front it is incomplete, presenting a wide interval between the anterior borders of the ilia. It forms the inferior volume of the abdomen proper cavity, which includes a number of parts of structures of the intra-abdominal proper e.g. historically the cavity of false pelvis has been described as containing the 'iliac colon' which is a segment of the descending colon within the volume of the false pelvis.

\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.
