The effect of somatic dysfunction on the thyroid is primarily which autonomic state?

• A. Hypersympathetic
• B. Parasympathetic
• C. Balanced autonomic
• D. No autonomic change

Answer: (A)

In somatic dysfunction, autonomic balance to nearby structures often tilts toward sympathetic activity, especially in the cervical region. The thyroid receives sympathetic innervation from upper thoracic and lower cervical segments via the sympathetic chain and cervical ganglia, which modulates its vascular flow and activity. When dysfunction affects the neck, this sympathetic influence tends to be heightened, producing a hypersympathetic state. Parasympathetic input to the thyroid is relatively minimal, so the effect is not a balanced or parasympathetic-dominant state. Therefore, the primary autonomic state impacting the thyroid in this context is hypersympathetic.
