Which statement best describes how somatic dysfunction can influence autonomic tone?

• A. SD has no effect on autonomic tone.
• B. SD influences autonomic tone only via reflexive pain responses.
• C. SD can influence autonomic tone and visceral function through mechanical or neurologic pathways.
• D. SD only affects the appearance of posture.

Answer: (C)

Somatic dysfunction can influence autonomic tone through mechanical and neurologic pathways. When a structure is out of place or restricted, changes in tissue tension and movement alter the afferent signals coming from muscles, fascia, and joints. That altered input is processed in the spinal cord and brainstem, leading to adjustments in autonomic outflow to the organs served by those levels. Additionally, somatic dysfunction can irritate or compress neural elements such as nerve roots or autonomic ganglia along the sympathetic chain, triggering reflex changes in sympathetic or parasympathetic activity. So, SD affects visceral function not just by a single mechanism, but through both mechanical signals and neural reflex pathways.
