The celiac ganglion receives preganglionic sympathetic fibers from which spinal levels via the greater splanchnic nerve?

• A T10–T11
• B T12–L2
• C L1–L3
• D T5–T9 ✓

Explanation

The greater splanchnic nerve arises from the thoracic sympathetic chain at levels T5–T9 (sometimes described as T5–T10) and carries preganglionic sympathetic fibers to the celiac ganglion, where they synapse. Postganglionic fibers then innervate the foregut derivatives. The lesser splanchnic nerve (T10–T11) goes to the aortorenal ganglion, and the least splanchnic nerve (T12) goes to the renal plexus. The lumbar splanchnic nerves (L1–L3) supply pelvic viscera.
