Medial and lateral arcuate ligaments of the diaphragm: attachment to the transverse process.
According to current anatomy textbooks, the diaphragmatic medial and lateral arcuate ligaments are attached to the transverse process of the first lumbar vertebra. In dissections of 15 human cadavers we found both arcuate ligaments attached to the transverse process of L2 (10 cases and L3 (5 cases). In no case were they attached to the transverse process of L1.
