The long ciliary nerves provide sensory innervation to the eyeball, including the cornea. In addition, they contain sympathetic fibers from the superior cervical ganglion to the dilator pupillae pupillÃ¦. musclehe sympathetic fibers to the dilator pupillae muscle mainly travel in the nasociliary nerve but there are also sympathetic fibers in the short ciliary nerves that pass through the ciliary ganglion without forming synapses.

The vagus nerve provides a speedy line of information to the brain from the gut, where battles with bacteria and viruses are continually raging. Knowledge of the vagus's role was a mystery until very recently, but we now know that you can learn about your body from your vagus. The longest nerve directly from the brain, the vagus sends messages to and receives messages from your gut and every other organ in your body. Because 85 percent of this huge nerve carries information back to the brain, it's the main mechanism by which your brain audits your body. The remaining 15 percent takes information from your brain to your body.
