1st Lumbar Nerve

The 1st lumbar nerve is one of thirty-one pairs of spinal nerves that originate from the spinal cord and the uppermost of the lumbar nerves in the lower back. Although spinal nerves do not have individual names, they are grouped according to the level from which they stem, and each nerve is numbered in sequence. Hence, there are five pairs of lumbar nerves (L1 - L5).
