1. A thickening of the fascia of the lumbar quadrate muscle, between the transverse process of the first lumbar vertebra and the twelfth rib on either side, that gives attachment to a portion of the diaphragm; lateral arcuate ligament.
2. A tendinous thickening of the fascia of the greater psoas muscle that extends from the body of the first lumbar vertebra to its transverse process on either side and from which a portion of the diaphragm arises; medial arcuate ligament.
3. A tendinous connection between the crura of the diaphragm that arches in front on the aorta; median arcuate ligament.
