Lumbar Plexus Anatomy -
The lumbar plexus forms within the substance of the psoas major muscle. It develops from the anterior rami of the first four lumbar spinal nerves (L1-L4), with occasional contributions from the subcostal nerve (T12). Unlike other nerve plexuses, the lumbar plexus has a more simplified structure, with each nerve typically receiving fibers from multiple spinal segments.
