The lumbar spinal nerve 4 (L4) is a spinal nerve of the lumbar segment.[1].
It originates from the spinal column from below the lumbar vertebra 4 (L4).
Muscles
L4 supplies many muscles, either directly or through nerves originating from L4. They are not innervated with L4 as single origin, but partly by L4 and partly by other spinal nerves. The muscles are:
- quadratus lumborum
- gluteus medius muscle
- gluteus minimus muscle
- tensor fasciae latae
- obturator externus
- inferior gemellus
- quadratus femoris
