|Latin||ligamentum arcuatum mediale|
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.
