Synonyms: Ramus communicans cum ganglio ciliare, Radix sensoria ganglii ciliaris
1. Definition
The radix longa ganglii ciliaris is a branch of the nasociliary nerve that contributes to the sensory innervation of the eye.
2. Course
The radix longa typically branches off from the nasociliary nerve as it passes between the two heads of the lateral rectus muscle. It runs anteriorly along the lateral side of the optic nerve and enters the ciliary ganglion at its posterosuperior end.
This nerve carries somatosensory fibers from the eyeball, which pass through the ciliary ganglion without synapsing. The cell bodies of these sensory fibers are located in the trigeminal ganglion.
3. Function
The radix longa ganglii ciliaris provides sensory innervation to the cornea and parts of the conjunctiva, playing a crucial role in conveying sensation from these structures.
