Sympathetic and parasympathetic connections of the ciliary and superior cervical ganglia

Note: The labeling has been corrected from that in Gray's Anatomy (1918). Gray has mislabeled the projections from the Edinger-Westphal nucleus in the midbrain as sympathetic rather than parasympathetic fibers and had labeled the sympathetic fibers from the superior cervical ganglion as postganglionic fibers without noting that they were sympathetic.
