Ciliary ganglion - Wikipedia
The ciliary ganglion contains postganglionic parasympathetic neurons that supply the ciliary muscle and the pupillary sphincter muscle. Because of the much larger size of the ciliary muscle, 95% of the neurons in the ciliary ganglion innervate it compared to the pupillary sphincter.

2023年10月24日 · The ciliary ganglion is one of four parasympathetic ganglia in the head. It is located behind the eye. Nerve fibers leave the brain and enter the ganglia. These fibers synapse (a junction between nerves where they communicate) with neurons going to the eye.
Parasympathetic Innervation to the Head and Neck - Anatomy
2024年9月5日 · The ciliary ganglion provides innervation to the sphincter pupillae muscle, which acts to constrict the pupil. If the ciliary ganglion is damaged, there is a loss of innervation to the sphincter pupillae. This results in a permanently dilated pupil that does not constrict in the presence of light.
Ciliary ganglion - Structure, Location, Function, Anatomy
2024年9月28日 · The ciliary ganglion is a small parasympathetic ganglion located within the orbit (eye socket). It is a key structure in the autonomic nervous system, acting as a relay point for nerve fibers traveling to the eye.
Ciliary body: anatomy and function - Kenhub
2023年10月30日 · The ciliary ganglion then gives off short ciliary nerves (i.e. postganglionic fibers) that innervate the ciliary body. There is scarce evidence that the ciliary body receives some sympathetic innervation via the superior cervical ganglion that inhibits the accommodation reflex.
Ciliary Ganglion — Ophthalmology Review
2016年4月25日 · Anatomy. Ciliary Ganglion. April 25, 2016. The ciliary ganglion lies temporal to the ophthalmic artery, inbetween the lateral rectus and optic nerve. It is approximately 1.5-2.0 cm (15-20 mm) posterior to the globe and 1.0 cm (10 mm) anterior to the Annulus of Zinn and the superior orbital fissure. Image credit: Wikipedia.

2023年3月4日 · The ciliary ganglion is one of four parasympathetic ganglia of the head and neck. It receives preganglionic parasympathetic fibers from the Edinger-Westphal nucleus via the oculomotor nerve. It supplies the eye via short ciliary nerves not only with parasympathetic fibers, but also with sensory and sympathetic fibers that pass through the ganglion.
Ciliary Ganglion | Complete Anatomy - Elsevier
The ciliary ganglion is a collection of postganglionic neuronal cell bodies that sit in the posterior aspect of the orbit, behind the eyeball.

2016年1月1日 · The ciliary ganglion (CG) is a parasympathetic ganglion responsible for miosis (pupil constriction) in response to light and accommodation. Parasympathetic, sympathetic, and sensory fibers run through the CG but only the parasympathetic fibers synapse in the CG. It is located in the posterior orbit. Anatomy.
