In brief: Hiccups
Hiccups are normally caused by irritation to the phrenic nerve.
This nerve originates from the spinal cord in the neck (cervicals 3, 4 and 5) on both sides and travels down to innervate the diaphragm. Irritation to the nerve causes spasms in the diaphragm which results in hiccups.

One of the trickiest calls in medicine is finding the cause of unexplained hiccups. Sometimes it's the sole side-effect of a medication. Since in sporadic hiccups the phrenic nerve isn't really "irritated", the impetus must be generated in the brain, which remains filled with mysteries!
