Voluntary control of the external urethral sphincter travels along which nerve?

1. The external urethral sphincter is voluntary skeletal muscle, so it needs a somatic nerve. 2. That nerve is the pudendal, arising in the sacral spinal cord and travelling in the sacral plexus. 3. The hypogastric nerves carry sympathetic traffic that suppresses detrusor contraction during filling. 4. The pelvic nerves carry the afferent stretch signals and parasympathetic outflow, not voluntary sphincter control. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 25 "The Urinary System", section 25.2 Gross Anatomy of Urine Transport_
