sensory - long ciliary nerves (from CN V1) and short ciliary nerves (from CN III)

The anterior of the sclera is mostly innervated by the long ciliary nerves whilst the posterior sclera is mainly innervated by the short ciliary nerves.

Afferent: CN5 ophthalmic
Efferent: CN7 facial nerve

Impulse reaches trigeminal nucleus in pons
4. Impulse transmitted to facial nerve nucleus in pons
5. Impulses sent via facial nerve to orbicularis oculi to close eyes

Nasociliary br. of ophthalmic nerve passes through ciliary ganglion without synapsing
