The abdominal wall is split into the posterior (back), lateral (sides) and anterior (front) walls. There is a common set of layers covering and forming all the walls: the deepest being the [[extraperitoneal fat]], the [[parietal peritoneum]], and a layer of [[fascia]] which has different names over where it covers (eg transversalis, psoas fascia). Superficial to these, but ''not'' present in the posterior wall are the three layers of muscle, the [[transversus abdominis]] (tranvserse abdominal muscle), the [[internal oblique|internal]] (obliquus internus) and the [[external oblique]] (obliquus externus). ==Layers of anterior abdominal wall== In [[human anatomy]], the layers of the abdominal wall are (from superficial to deep): * [[Skin]] * [[Fascia]] ** [[Camper's fascia]] - fatty superficial layer ** [[Scarpa's fascia]] - deep fibrous layer * [[Muscle]] ** [[External oblique muscle]] ** [[Internal oblique muscle]] ** [[Transverse abdominal muscle]] * [[Fascia transversalis]] * [[Peritoneum]] * there's NO deep abdominal fascia not to restrict abdominal distention e.g. respiration and pregnancy ==Inner surface== The surface contains several ligaments separated by fossae: {| class="wikitable" | '''Ligament/fold''' || '''Remnant of''' || '''Lateral fossa''' || '''Hernia''' |- | [[median umbilical ligament]] || [[urachus]] || [[supravesical fossa]] || - |- | [[medial umbilical ligament]] || [[umbilical artery]] || [[medial inguinal fossa]] || [[direct inguinal hernia]] |- | [[lateral umbilical fold]] || inferior epigastric vessels || [[lateral inguinal fossa]] || [[indirect inguinal hernia]] |} ==See also== *[[Peritoneum]] *[[Human abdomen]] *[[Terms for anatomical location]] *[[Abdominal exercise]] ==External links== * {{MUNAnatomy|digest/abwall}} * {{NormanAnatomy|skel&wallsabd}} - "Skeleton of the Abdomen", Wesley Norman, PhD, DSc * {{MeshName|Abdominal+Wall}} *[http://www.portfolio.mvm.ed.ac.uk/studentwebs/session5/37/ALBL_Anterolateralwall.htm Anterolateral Abdominal Wall] - [[University of Edinburgh]] Faculty of Medicine *[http://anatomy.uams.edu/anatomyhtml/antabdominalwall.html Muscles of the Anterior Abdominal Wall] - [[University of Arkansas]] {{Torso general}} [[Category:Abdomen]]
