The great splanchnic nerve primarily consists of:
d. Myelinated preganglionic efferent and visceral afferent fibres
It originates from the sympathetic ganglia (typically the fifth to ninth or tenth thoracic ganglia) and carries preganglionic sympathetic fibers that synapse in the celiac ganglion, as well as afferent fibers that carry sensory information from the abdominal organs.
