Anatomical terms of neuroanatomy []

The lumbar splanchnic nerves are splanchnic nerves that arise from the lumbar part of the sympathetic trunk and travel to an adjacent plexus near the aorta. They originate from L1 and L2.

These nerves contain preganglionic sympathetic and general visceral afferent fibers.

The site of synapse is found in the inferior mesenteric ganglion and the postsynaptic fibers innervate the smooth muscle and glands of the pelvic viscera and hindgut.
