AThe celiac plexus and splanchnic nerves
BThe pudendal and hypogastric nerves
CThe vagus and the phrenic nerves
DThe sacral plexus and pelvic nerves
Answer & Solution
Correct answer: A. The celiac plexus and splanchnic nerves
1. Renal blood flow is under autonomic control, and the traffic is sympathetic.
2. Those sympathetic neurons reach the kidney through the celiac plexus and the splanchnic nerves.
3. The pudendal and pelvic nerves serve micturition at the bladder, a different part of the system.
4. The vagus carries parasympathetic fibres to thoracic and abdominal viscera but is not the renal route named here.
