In anatomy, 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 according to what it covers (e.g., transversalis, psoas fascia).
In medical vernacular, the abdominal wall most commonly refers to the layers composing the anterior abdominal wall which, in addition to the layers mentioned above, includes the three layers of muscle: the transversus abdominis (transverse abdominal muscle), the internal (obliquus internus) and the external oblique (obliquus externus).

Famous quotes containing the word wall:
“The poisoned rat in the wall
Cuts through the wall like a knife,
Then blind, drying, and small
And driven to cold water,
Dies of the water of life....”
