Origin The long ciliary nerves branch from the nasociliary nerve as it crosses the optic nerve (CN II). Course Accompanied by the short ciliary nerves, the long ciliary nerves pierce and enter the posterior part of the sclera near where it is entered by the optic nerve, then run anterior-ward between the sclera and the choroid. Ver mais The long ciliary nerves are 2-3 nerves that arise from the nasociliary nerve (itself a branch of the ophthalmic branch (CN V1) of the trigeminal nerve (CN V)).

Web4 de mar. de 2024 · The ciliary ganglion is one of four parasympathetic ganglia of the head and neck. It receives preganglionic parasympathetic fibers from the Edinger-Westphal nucleus via the oculomotor nerve. It supplies the eye via short ciliary nerves not only with parasympathetic fibers, but also with sensory and sympathetic fibers that pass through … WebThese axons enter the eyeball by way of the long posterior ciliary nerves.
