The second lumbar spinal nerve (L2) [2] originates from the spinal column from below the lumbar vertebra 2 (L2). L2 supplies many muscles, either directly or through nerves originating from L2. They may be innervated with L2 as single origin, or be innervated partly by L2 and partly by other spinal nerves. The muscles are: quadratus lumborum ...
The obturator nerve originates from the anterior divisions of the L2, L3, and L4 spinal nerve roots. [1] It descends through the fibers of the psoas major, and emerges from its medial border near the brim of the pelvis.
The lumbar region L1 and L2 consist of neurons that innervate the adrenal gland, ureter, bladder, the lower extremities. The upper two lumbar ganglia (L1 and L2) of the sympathetic chain also give rise to the lumbar splanchnic nerves. Splanchnic nerves are paired visceral nerves carrying preganglionic sympathetic and general visceral afferent ...
The femoral nerve is the major nerve supplying the anterior compartment of the thigh. It is the largest branch of the lumbar plexus, and arises from the dorsal divisions of the ventral rami of the second, third, and fourth lumbar nerves (L2, L3, and L4). [1] [2]
The lateral femoral cutaneous nerve (LFCN) originates from the lumbar plexus and contains fibers from lumbar nerves L2 and L3. [7] [4] [2] [3] The LFCN then traverses to the lateral border of the psoas major muscle, crosses the iliacus muscle, and continues to the anterior superior iliac spine (bony landmark).

Descending nerve roots continue as the cauda equina [35] at levels L2–S5 below the conus medullaris before exiting through intervertebral foraminae. [39] Thus it is not a true spinal cord syndrome since it is nerve roots that are damaged and not the cord itself; however, it is common for several of these nerves to be damaged at the same time ...
