Study Notes
- Numerous nerves innervate structures in the orbit, including the optic nerve, oculomotor nerve, trochlear nerve, abducent nerve, and autonomic nerves.
- The optic nerve carries afferent fibers from the retina to the brain and is surrounded by the cranial meninges.
- Increased intracranial pressure can cause papilledema.
- The oculomotor nerve divides into superior and inferior branches and innervates several muscles in the orbit.
- The inferior branch also carries parasympathetic fibers to the ciliary ganglion, which innervate the sphincter pupillae and ciliary muscles.
- The trochlear nerve innervates the superior oblique muscle.
- The abducent nerve supplies the lateral rectus muscle.
- Postganglionic sympathetic fibers arise from the thoracic spinal cord and innervate the dilator pupillae muscle.
- These fibers can reach the eyeball through the ciliary ganglion or long ciliary nerves.
- Autonomic nerves also play a role in innervating orbital structures.
