Quick Facts
Location: Posterior orbit.
Branches: Receives preganglionic parasympathetic fibers from the oculomotor nerve and send fibers to the short ciliary nerves.
Supply: Sensory and parasympathetic. Ciliary muscle and sphincter pupillae.
Location
The ciliary ganglion is a collection of postganglionic neuronal cell bodies that sit in the posterior aspect of the orbit, behind the eyeball.
Branches
The ciliary ganglion receives preganglionic parasympathetic fibers from the oculomotor nerve. The postganglionic fibers leaving the otic ganglion join up with the short ciliary nerves.
Supplied Structures
The fibers of the ciliary ganglion target the ciliary muscle and sphincter pupillae.

Ciliary Ganglion
The avian ciliary ganglion is a parasympathetic ganglion composed of two populations of neurons: large ciliary neurons that innervate the iris and ciliary muscle, and small choroid neurons that innervate vasculature in the choroid layer of the eye.
