Uterine pathology will manifest a sympathetic viscerosomatic reflex in which area?

• A. T9-L2, bilateral
• B. S2-S4
• C. T1-T4
• D. C8-T1

Answer: (A)

Visceral afferents from the uterus travel with the sympathetic nerves coming from the thoracolumbar spine, primarily around T10 to L2. Because of this, a uterine problem can produce a viscerosomatic reflex manifested as somatic dysfunction in the corresponding paraspinal tissues. The paraspinal muscles and related tissues in the lower thoracic to upper lumbar region, on both sides, are the typical sites for such reflexes, roughly spanning the T9 through L2 area. The other options don’t fit because they map to different autonomic pathways: S2–S4 relates to pelvic parasympathetics, T1–T4 to other thoracic structures, and C8–T1 to the cervicothoracic region, not the uterus.
