Question

postganglionic sympathetic axons are carried from the sympathetic trunk to the spinal nerve by the
multiple choice
white rami.
superior cervical ganglion.
gray rami.
splanchnic nerves.
pterygopalatine ganglion.

Explanation:

Postganglionic sympathetic axons are unmyelinated. Gray rami contain unmyelinated postganglionic sympathetic fibers. White rami contain myelinated preganglionic fibers. Superior cervical ganglion, splanchnic nerves, and pterygopalatine ganglion are not structures that carry postganglionic sympathetic axons from the sympathetic trunk to the spinal nerve in the way described.

Answer:

gray rami.
