Least splanchnic nerve originates from which spinal level?

Explanation:
The key idea here is that splanchnic nerves carry preganglionic sympathetic fibers that bypass the sympathetic chain and synapse in prevertebral ganglia. Each splanchnic nerve is named for the spinal level where its fibers originate. The least splanchnic nerve comes from the twelfth thoracic spinal level, and it typically fibers synapse in the aorticorenal ganglion or contribute to the renal plexus as it reaches the kidneys. This differentiates it from the greater splanchnic nerve (higher thoracic levels) and the lesser splanchnic nerve (lower thoracic levels). So, the origin is the twelfth thoracic level.
