Olfactory!
Cranial Nerve 2 - Optic Nerve
Nerve Cells are capable of transmitting [relaying] bio-information.
Spinal cord
The cranial nerve that is tested in the visual acuity test is the optic nerve, also known as cranial nerve II. It is responsible for transmitting visual information from the retina to the brain.
Actually, there are three cranial nerves that are completely sensory: Olfactory nerve, Optic nerve and the Vestibulocohlear nerve. The Optic nerve is responsible for sensory information for vision, the Olfactory nerve is responsible for sensory information coming from the nose and the Vestibulocohlear (the craziest word to spell) involves sensory information for hearing (get it?- cohlear, ear) and equilibrium.
The nerve that is also known as the acoustic or auditory nerve is the vestibulocochlear nerve (cranial nerve VIII). It is responsible for transmitting auditory and balance information from the inner ear to the brain.

Nerve cell
With an inflammation of the middle and inner ear, there is also inflammation of auditory nerve (which is responsible for transmitting information to the brain; sound and balance). When this nerve becomes irritated, it can make you feel like your world is spinning and thus can make you feel sick to your stomach with the accompanying dizziness and nausea.
