The ciliary ganglion is small parasympathetic ganglion lying in the orbit between the optic nerve and the lateral rectus muscle that is associated with the nasociliary nerve (a branch of the ophthalmic division of the trigeminal nerve). The ciliary ganglion is a part of the nervous pathway responsible for the constriction of the pupil and accomodation for image focusing, as well as sensation from the cornea.
It also receives the Sympathetic Root, which is a series of fibers coming from the Budge Cilio-Spinal tract, coming from the sympathetic ganglia in C8-T2, which carries the nervous fibers that innervate the iris dilator muscle.
