[2025-10-02T02:59:02.322482] [PI reasoning] **Evaluating adrenal gland nerve supply**

I need to answer the question about the nerve supply to the adrenal gland and provide the best option with reasoning and citations. The adrenal medulla is supplied by preganglionic sympathetic fibers from the thoracic spinal cord, specifically T10-L1, which bypass the sympathetic chain to connect with chromaffin cells. Option A suggests these fibers come from the sympathetic chain, which is slightly misleading since they do bypass it. Nonetheless, it's the correct choice. I'll make sure to add citations for accuracy.
