Cilium projections from living cells that have locomotive or sensory functions. Ciliary body - the circumferential tissue inside the eye. It measures 1- 2 millimeters in diameter and contains approximately 2500 neurons.
Its parasympathetic fibers from the Edinger Westphal nucleus run in the oculomotor nerve AB2 and cross over to theganglion as oculomotor root AB3 para-sympathetic root. The postganglionic axons innervate two eye muscles. Three types of axons enter the ciliary ganglion but only the preganglionic parasympathetic axons synapse there.
The ciliary ganglion is a parasympathetic ganglion located in the posterior orbit. A small autonomic ganglion on the nasociliary branch of the ophthalmic nerve receiving preganglionic fibers from the oculomotor nerve and sending postganglionic fibers to the ciliary muscle and to the sphincter pupillae called also lenticular ganglion Learn More about ciliary ganglion. Gross anatomy smallest of the ganglia 2 mm in size located posterolaterally in the intraconal spa.
Ciliary may refer to. The ciliary ganglion is a bundle of nerve parasympathetic ganglion located just behind the eye in the posterior orbitIt is 12 mm in diameter and in humans contains approximately 2500 neurons. The ciliary ganglion lies temporal to the ophthalmic artery inbetween the lateral rectus and optic nerve.
- information from eyeball enters short ciliary nerve branches and goes through sensory root which joins the nasociliary nerve of V1 and goes to SA cell bodies in the trigeminal ganglion What are the functional components of the short ciliary nerves of the ciliary ganglion. The entering axons are arranged into three roots of the ciliary ganglion which join enter the posterior surface of the ganglion. Pathway to ciliary body muscles and sphincter pupillae.
The ciliary ganglion is supplied by fibres from the Edinger-Westphal nucleus associated with the oculomotor nerve. The ganglion which is approximately the size of a pin head lies posteriorly in the orbital cavity between the optic nerve and lateral rectus muscle. Ciliary muscle - eye muscle used for focusing.
It measures 1- 2 millimeters in diameter and contains approximately 2500 neurons. The ciliary ganglion AB1 is a small flat body lying laterally to the optical nerve in the orbit. Preganglionic axons from the Edinger-Westphal nucleus form synapses with these cells.
Edinger-Westphal nucleus in brain stem - CN III - inferior division of CN III - ciliary ganglion - synapse with parapost - short ciliary nerves - sphincter pupillae and ciliary body muscles. Ciliary nerves disambiguation Ciliary processes - folded layers in the anterior of the eye. Cochlear ganglion the sensory ganglion located within the spiral canal of the modiolus.
It is situated anteriorly to the superior orbital fissure between the lateral rectus muscle and the optic nerve. It is topographically connected to nasociliary nerve branch of ophthalmic division of trigeminal n erve It is functionally related to Oculomotor nerve. It is a relay station for fibers supplying sphincter pupillae and ciliaris muscle.
The ciliary ganglion is approximately 3 mm in size and located 23 mm posterior to the globe and lateral to the optic nerve. The ciliary ganglion is located within the bony orbit. This ganglion contains the cell bodies of the postganglionic pupilloconstrictor neurons which innervate the sphincter muscle of the iris.
The ciliary ganglion lies within the lateral orbitbetween the optic nerve and lateral rectus muscle. Medical Definition of ciliary ganglion. Parapre cell bodies of ciliary ganglion.

It consists of bipolar cells that send fibers peripherally to the organ of Corti and centrally to the cochlear nuclei of the brainstem. These neurons supply the pupillary sphincter muscle which constricts the pupil and the ciliary muscle which contracts to make the lens.
