Which autonomic nerve innervates the urinary bladder, uterus, and external genitalia?

Autonomic splanchnic nerve innervates the urinary bladder, uterus, and external genitalia, sympathetic nerve that originates from the paravertebral thoracic ganglia, but does not innervate thoracic viscera, but abdominal. There are two splanchnic nerves: greater (of the V-IX ganglia) and minor (of the X and XI ganglia). Sometimes, a third appears, the most caudal, called imo (ganglion XII). All of them end in the celiac plexus.
