also along short ciliary nerve to dilator pupulae The fibers (nasal ciliary nerve -> long ciliary nerve) innervate the dilator muscles of the iris and the smooth muscle (Müller's muscle) in the upper and lower eyelid (inferior retractors). Here the oculosympathetic fibers exit the internal carotid artery in close proximity to the trigeminal ganglion and the sixth cranial nerve and join the 1st division of the trigeminal nerve (Ophthalmic division) to enter the orbit. enters the cranium within the adventitia of the internal carotid artery into the cavernous sinus. The superior cervical ganglion is located near the angle of the mandible and bifurcation of the common carotid artery. exits the spinal cord and travels in the cervical sympathetic chain through the brachial plexus, over the pulmonary apex and synapses in the superior cervical ganglion. descends caudally from the hypothalamus to the first synapse in the cervical spinal cord (C8-T2 level-also called the ciliospinal center of Budge).
