| ciliary zone | The outer, wider zone of the anterior surface of the iris, separated from the pupillary zone by the collarette. Synonym: zona ciliaris. (05 Mar 2000) |
| ciliary zonule | A series of delicate meridional fibres arising from the inner surface of the orbiculus ciliaris that run in bundles between, and in a very thin layer over, the ciliary processes; at the inner border of the corona, the fibres diverge into two groups that are attached to the capsule on the anterior and posterior surfaces of the lens close to the equator; the spaces between these two layers of fibres are filled with aqueous humor. Synonym: zonula ciliaris, apparatus suspensorius lentis, suspensory ligament of lens, Zinn's zonule. (05 Mar 2000) |
| pigmented layer of ciliary body | The continuation of the pigment layer of the retina onto the posterior aspect of the ciliary body. Synonym: pigmented layer of ciliary body. (05 Mar 2000) |
| motor root of ciliary ganglion | A branch of the oculomotor nerve supplying parasympathetic preganglionic nerve fibres to the ciliary ganglion. Synonym: radix parasympathica ganglii ciliaris, radix oculomotoria ganglii ciliaris, motor root of ciliary ganglion, oculomotor root of ciliary ganglion, radix brevis ganglii ciliaris, short root of ciliary ganglion. (05 Mar 2000) |
| sensory root of ciliary ganglion | Sensory fibres passing from the eyeball through the ciliary ganglion to their cell bodies in the trigeminal ganglion via the nasociliary nerve. Synonym: radix sensoria ganglii ciliaris, ramus communicans nervi nasociliaris cum ganglio ciliari, radix nasociliaris, long root of ciliary ganglion, nasociliary root, radix longa ganglii ciliaris. (05 Mar 2000) |

| short root of ciliary ganglion | A branch of the oculomotor nerve supplying parasympathetic preganglionic nerve fibres to the ciliary ganglion. Synonym: radix parasympathica ganglii ciliaris, radix oculomotoria ganglii ciliaris, motor root of ciliary ganglion, oculomotor root of ciliary ganglion, radix brevis ganglii ciliaris, short root of ciliary ganglion. (05 Mar 2000) |
| sympathetic root of ciliary ganglion | Postganglionic fibres,having cell bodies in the superior cervical ganglion, branching from the carotid plexus passing through the ciliary ganglion without synapse to reach the eyeball. Synonym: radix sympathica ganglii ciliaris. (05 Mar 2000) |

Synonym: radix parasympathica ganglii ciliaris, radix oculomotoria ganglii ciliaris, motor root of ciliary ganglion, oculomotor root of ciliary ganglion, radix brevis ganglii ciliaris, short root of ciliary ganglion. (05 Mar 2000) |
| embryonal tumour of ciliary body | <tumour> An epitheliomatous tumour of the nonpigmented layer of the ciliary epithelium. Synonym: embryonal tumour of ciliary body. (05 Mar 2000) |
| long ciliary nerve | <anatomy, nerve> One of two or three branches of the nasociliary nerve, which by-pass the ciliary ganglion, supplying post-synaptic sympathetic fibres for the dilator pupillae muscle and sensory fibres for the ciliary muscles, iris, and cornea. Synonym: nervus ciliaris longus. (05 Mar 2000) |
| long root of ciliary ganglion | Sensory fibres passing from the eyeball through the ciliary ganglion to their cell bodies in the trigeminal ganglion via the nasociliary nerve. Synonym: radix sensoria ganglii ciliaris, ramus communicans nervi nasociliaris cum ganglio ciliari, radix nasociliaris, long root of ciliary ganglion, nasociliary root, radix longa ganglii ciliaris. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |
