Rib raising is most directly related to modulation of which neural structure?

• A. Sympathetic chain ganglia
• B. Vagus nerve
• C. Phrenic nerve
• D. Dorsal root ganglia

Answer: (A)

Rib raising targets the sympathetic nervous system by engaging the thoracic sympathetic chain ganglia that lie along the vertebral column near the heads of the ribs. The maneuver moves the ribs in a way that mechanically influences the tissues around these ganglia, helping to modulate sympathetic outflow to thoracic organs and reduce excessive sympathetic tone. The vagus nerve is parasympathetic and not the primary focus here, the phrenic nerve supplies the diaphragm and isn’t the target of this technique, and the dorsal root ganglia are sensory structures not directly modulated by rib movement. So the structure most directly affected is the thoracic sympathetic chain ganglia.
