A viscerosomatic reflex consisting of bilateral grouped somatic dysfunction from T5 to T9 is most consistent with pathology affecting which organ?

• A. Pancreas
• B. Stomach
• C. Liver
• D. Gallbladder

Answer: (A)

Foregut organs share sympathetic input through the greater splanchnic nerves that arise from the T5–T9 levels. When you observe somatic dysfunction that is bilateral and grouped across T5 through T9, it points to an organ in the midline foregut region being affected. The pancreas sits in the midline and is innervated by these same T5–T9 segments, so pancreatic pathology commonly manifests as bilateral somatic dysfunction across that thoracic range. While other foregut organs like the stomach (often left-sided) or liver/gallbladder (more right-sided and typically mapped to T7–T9) can also involve these levels, the bilateral, midline pattern spanning T5–T9 most specifically aligns with the pancreas.
