CILIARY GANGLION-ROOTS

1. PARASYMPATHETIC - pre-ganglionic fibers arise from the Edinger-Westphal nucleus in the midbrain and relay in the ganglion.

2. SYMPATHETIC - post-ganglionic fibers arise from the cavernus sinus plexus and pass through the ganglion without relay.

3. SENSORY - branch of the nasociliary nerve, passes through the ciliary ganglion without relay to the trigeminal ganglion.

4. SENSORY SUPPLY - whole eye, sclera, cornea, iris, ciliary body; but not the conjunctiva. Division of the root abolishes the corneal reflex but not conjunctival reflex.
