These pierce the intercostales externi and the obliquus externus abdominis, in the same line as the lateral cutaneous branches of the upper thoracic nerves, and divide into anterior and posterior branches, which are distributed to the skin of the abdomen and back; the anterior branches supply the digitations of the obliquus externus abdominis ...

The iliohypogastric nerve runs posterior to the psoas major on its proximal lateral border to run laterally and obliquely on the anterior side of quadratus lumborum.Lateral to this muscle, it pierces the transversus abdominis to run above the iliac crest between that muscle and abdominal internal oblique.
The hypogastric nerves begin where the superior hypogastric plexus splits into a right and left hypogastric nerves. The hypogastric nerves continue inferiorly on their corresponding side of the body, where they descends into the pelvis to form the inferior hypogastric plexuses. [1] The hypogastric nerves likely contain three nerve fibers types: [2]

In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum ...
The thoracolumbar fascia (lumbodorsal fascia or thoracodorsal fascia) is a complex, [1]: 1137 multilayer arrangement of fascial and aponeurotic layers forming a separation between the paraspinal muscles on one side, and the muscles of the posterior abdominal wall (quadratus lumborum, and psoas major [1]: 1137 ) on the other.
