The reflex arc of the hiccup has 3 components: the afferent limb composed of phrenic, vagus, and sympathetic nerves; a central processor in the midbrain; and the efferent limb composed of the phrenic nerve supplying the diaphragm and intercostal nerves supplying the intercostal muscle fibers [3].

Loss of inhibitory control from the brain via the spinal cord leads to uninhibited excitation of the monosynaptic spinal reflex arc. [5] The muscles, therefore, fire on their own, which causes spasticity.

Dry eye syndrome, a disease that is reported to affect over 30% of the population over 50 years of age, can be the result of an altered or inadequate tear film and it is thought to be associated with poor regulation of tear production via these sensory neurons in the tear reflex arc. (16-17) Ocular surgery, particularly laser refractive surgery, can negatively affect the ocular surface and tear film dynamics resulting in dry eye syndrome.
