The medial arcuate ligament (also medial lumbocostal arch and internal arcuate ligament) is a tendinous fascia that arches over the psoas major muscle as it passes posterior the diaphragm.
Medial arcuate ligament
The diaphragm. Under surface. (Med. arcuate ligament visible at bottom center left.)
The medial arcuate ligament is an arch in the fascia covering the upper part of the psoas major. It is attached to the side of the body of the first or second lumbar vertebra, laterally, it is fixed to the front of the transverse process of the first and, sometimes also, to that of the second lumbar vertebra.
The sympathetic chain enters the abdomen by passing deep into this ligament of the diaphragm. This is in contrast to the parasympathetic Vagus nerve which passes through the esophageal hiatus.
