Sensory fibers from the eyeball (the cornea, iris and ciliary body) run posteriorly through the short ciliary nerves and pass through the ciliary ganglion without forming synapses. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group Eyes are organs that detect Light, and send signals along the Optic nerve to the visual areas of the brain The cornea is the transparent front part of the Eye that covers the iris, Pupil, and Anterior chamber. The iris consists of Pigmented Fibrovascular tissue known as a stroma. The ciliary body is the circumferential tissue inside the Eye composed of the Ciliary muscle and Ciliary processes. The branches of the Ciliary ganglion are the short ciliary nerves. The ciliary ganglion is a parasympathetic Ganglion located in the posterior orbit. Chemical synapses are specialized junctions through which Neurons signal to each other and to non-neuronal cells such as those in Muscles or Glands They leave the ciliary ganglion in the sensory root of ciliary ganglion, which joins the nasociliary nerve. The nasociliary nerve is a branch of the Ophthalmic nerve. It is intermediate in size between the two other main branches of the ophthalmic nerve the Frontal nerve
The nasociliary nerve is a branch of the ophthalmic nerve, one of the three branches (V1) of the trigeminal nerve. The ophthalmic nerve is one of the three branches of the Trigeminal nerve, the fifth Cranial nerve. The trigeminal nerve (the fifth Cranial nerve, also called the fifth nerve or simply V) is responsible for sensation in the face The trigeminal nerve is the main sensory nerve of the face.
Sensory fibers from other parts of the eye run through the long ciliary nerves and other peripheral branches of the ophthalmic nerve. The long ciliary nerves, two or three in number are given off from the Nasociliary, as it crosses the Optic nerve. The ophthalmic nerve is one of the three branches of the Trigeminal nerve, the fifth Cranial nerve.
Variability
The exact distribution of sensory fibers, like the distribution of sympathetic fibers, is anatomically variable. There are alternate pathways to the eye for both sympathetic and sensory fibers, and the precise anatomy varies from person to person. Since the result is the same regardless of how the fibers reach the eye, the presence of sympathetic and sensory fibers in the ciliary ganglion (the contributions of the “sensory” and “sympathetic” roots) is of no functional significance.
