The fifth cranial nerve, called the trigeminal nerve, is apparently responsible for sneezes.
bilby commented on the word trigeminal
"A sneeze is usually triggered by an irritation in the nose, which is sensed by the trigeminal nerve, a cranial nerve responsible for facial sensation and motor control. This nerve is in close proximity to the optic nerve, which senses, for example, a sudden flood of light entering the retina. As the optic nerve fires to signal the brain to constrict the pupils, the theory goes, some of the electrical signal is sensed by the trigeminal nerve and mistaken by the brain as an irritant in the nose. Hence, a sneeze."

"When cold water touches the face, an impulse travels along the trigeminal and vagus nerves to the central nervous system and lowers the metabolic rate. The pulse slows down and the blood pools where it's needed most, in the heart and skull. It's a sort of temporary hibernation that drastically reduces the body's need for oxygen. Nurses will splash ice water on the face of a person with a racing heart to trigger the same reaction."

Ooh, bad memories. My first ever laptop was a brand called Tri-Gem. And it was a lemon. Worked fine only briefly and then the AC power supply died. By then the company seemed to not exist and I ended up having to get a new power supply custom made. But of course there were no BIOS updates available, etc., which in those days were pretty necessary to keep things ticking at least passably well. Landfill.
