Visceral autonomic mapping for the ovaries is most consistent with which level and division?

• A. Ovaries — T10-T11 Sympathetic
• B. Ovaries — S2-S4 Parasympathetic
• C. Ovaries — C3-C5 Sympathetic
• D. Ovaries — L1-L2 Parasympathetic

Answer: (A)

Understanding how visceral autonomic innervation maps to spinal levels helps explain why the ovaries are tied to a thoracic sympathetic level. The ovaries receive sympathetic preganglionic fibers from the mid-thoracic spinal cord, specifically around T10 to T11. These fibers travel with the thoracic splanchnic nerves to prevertebral ganglia and then follow the gonadal vessels to reach the ovaries. Pain and afferent signals from the ovaries are referred to the T10–T11 dermatomes, which aligns with this sympathetic origin. Parasympathetic supply to pelvic organs comes from sacral levels (S2–S4) via the pelvic splanchnic nerves, not from cervical or lumbar/pelvic parasympathetic pathways, so those options don’t match ovarian innervation. Therefore, the combination that fits is ovaries with sympathetic fibers at T10–T11.
