The celiac ganglion receives preganglionic sympathetic fibers from which spinal cord levels?

• A T5–T12 via the greater and lesser splanchnic nerves ✓
• B T1–T4 via the cardiac accelerator fibers
• C L1–L3 via the lumbar splanchnic nerves
• D S2–S4 via the pelvic splanchnic nerves

Explanation

The celiac ganglion, the largest prevertebral ganglion, receives preganglionic sympathetic fibers via the greater splanchnic nerve (T5–T9) and lesser splanchnic nerve (T10–T11); the least splanchnic (T12) mainly supplies the aortorenal ganglion. These preganglionic fibers pass through the paravertebral chain without synapsing. T1–T4 fibers supply cardiac accelerator fibers. Lumbar splanchnic nerves (L1–L3) supply pelvic organs and lower limb vasculature. Pelvic splanchnics (S2–S4) are parasympathetic.
