The cranial nerves can be classified as special sensory, (primarily) motor, or mixed sensory and motor. Olfactory Nerve (N I) The olfactory nerve is a special sensory cranial nerve that is responsible for the sense of smell.
Information concerning olfaction goes directly to the cerebrum in the olfactory tract. This is the only cranial nerve whose sensory information goes directly to the cerebrum rather than being relayed by the thalamus. The optic nerve is a special sensory cranial nerve that carries visual information. The ganglion cells of the retina have axons that pass through the optic nerves.
