Continuum MULTIPLE-CHOICE QUESTIONS

Most evidence suggests that the major efferent limb of the inflammatory reflex is carried in: A. The sympathetic chain B. The phrenic nerve C. The vagus nerve D. Postganglionic sympathetics arising in the stellate ganglia E. The long thoracic nerve Correct Answer: The correct answer is C. Evidence suggests that information leaving the central nervous system regarding regulation of inflammation is carried mainly in the vagus nerve. The sympathetic chain is the origin of postganglionic fibers for sympathetic innervation of visceral organs. The phrenic nerve carries motor axons for the diaphragm, and the postganglionic sympathetics are destined to provide sympathetic innervation to the heart, lungs, and neighboring structures....
