Long ciliary nerves

From Wikipedia, the free encyclopedia

Nerve: Long ciliary nerves

Nerves of the orbit, and the ciliary ganglion. Side view.
Latin	nervi ciliares longi
Gray's	subject #200 888
From	Nasociliary nerve
Dorlands/Elsevier	n_05/12565377

The long ciliary nerves, two or three in number, are given off from the nasociliary, as it crosses the optic nerve.

They accompany the short ciliary nerves from the ciliary ganglion, pierce the posterior part of the sclera, and running forward between it and the choroid, are distributed to the iris and cornea.

The long ciliary nerves provide sensory innervation to the eyeball. In addition, they might contain sympathetic fibers from the superior cervical ganglion to the Dilator pupillæ muscle.

Nerves of head and neck: the cranial nerves

I-IV: olfactory - optic - oculomotor (superior branch, inferior branch) - trochlear

V: trigeminal: trigeminal ganglion
V1: ophthalmic: lacrimal - frontal (supratrochlear, supraorbital) - nasociliary (long root of ciliary, long ciliary, infratrochlear, posterior ethmoidal, anterior ethmoidal) - ciliary ganglion (short ciliary)
V2: maxillary: middle meningeal - in the pterygopalatine fossa (zygomatic, zygomaticotemporal, zygomaticofacial, sphenopalatine, posterior superior alveolar)
in the infraorbital canal/infraorbital nerve (middle superior alveolar, anterior superior alveolar)
on the face (inferior palpebral, external nasal, superior labial, infraorbital plexus) - pterygopalatine ganglion (deep petrosal, nerve of pterygoid canal)
branches of distribution (greater palatine, lesser palatine, nasopalatine, pharyngeal)
V3: mandibular: meningeal - medial pterygoid - anterior (masseteric, deep temporal, buccal, lateral pterygoid)
posterior (auriculotemporal, lingual, inferior alveolar, mylohyoid, mental) - otic ganglion - submandibular ganglion

VI: abducens

VII: facial: nervus intermedius - geniculate - inside facial canal (greater petrosal, nerve to the stapedius, chorda tympani)
at exit from stylomastoid foramen (posterior auricular, digastric - stylohyoid)
on face (temporal, zygomatic, buccal, mandibular, cervical)

VIII: vestibulocochlear: cochlear (striae medullares, lateral lemniscus) - vestibular (Scarpa's ganglion)

IX: glossopharyngeal: nucleus ambiguus - ganglia (superior, petrous) - tympanic (tympanic plexus, lesser petrosal) - carotid sinus - pharyngeal branches - pharyngeal plexus

X: vagus: ganglia (jugular, nodose) - Alderman's nerve - in the neck (pharyngeal branch, superior laryngeal ext and int, recurrent laryngeal)
in the thorax (pulmonary branches, esophageal plexus) - in the abdomen (gastric plexuses, celiac plexus, gastric plexus)

XI: accessory XII: hypoglossal
