The '''abdominal wall''' represents the boundaries of the [[abdominal cavity]]. 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]]
|}
