Ciliary ganglion is one of the parasympathetic ganglion of head and neck. It have connections with parasympthetic , sensory ,and sympathetic fiber. So let's see where it is located. CILIARY GANLION is located between lateral rectus and optic nerve. It is placed in the posterior wall of orbit about 1cm anterior to the medial end of Superior orbital fissure. In the above diagram you see the cross section of cranium from above. The green dot show the location of CILIARY ganlion. Now let's see it's connections. Parasympthetic connections Pre ganglionic parasympathetic fiber start from edinger west phal nucleus (which is a parasympathetic nucleus) travel with 3rd cranial nerve enter into ciliary ganglion and terminates here. The post ganglionic parasympathetic fiber comes out as 8 to 10 short ciliary nerve which divide into 15 to 20 branches which pierces the eye ball and supply the ciliaris muscle and constrictor pupilli.
