Fig. 45-7. The ciliary ganglion and its connections, lateral aspect. Sympathetic fibers are also distributed to the superior tarsal muscle (Fig. 45-10). Horner syndrome results from interruption of the sympathetic pathway anywhere from the hypothalamus (diencephalon) to the eye, e.g., by a tumor or by intracranial thrombosis. Fibers: parasympathetic (green), sympathetic (red), and afferent (blue); preganglionic (continuous lines) and postganglionic (interrrupted and dotted lines).
