Twelve pairs of peripheral nerves connect to the brain rather than the spinal cord. These nerves are designated by Roman numerals preceded by N. In addition, each pair has a name. 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. The receptors of these neurons are found in the olfactory epithelium and the axons pass through the cribriform plate of the ethmoid bone.
