olfactory nerve the first cranial nerve; it is purely sensory and is concerned with the sense of smell. The nerve cell bodies are situated in the olfactory area of the mucous membrane of the nose. The nerve fibers lead upward through openings in the ethmoid bone, connect with the cells of the olfactory bulb, and then pass inward to the cerebrum. See Appendix 2-5.

RIGHT OLFACTORY NERVE

olfactory nerve

A sensory nerve with neuronal cell bodies located in the olfactory epithelium (a yellowish-brown thickened patch of epithelium found along the upper back walls of the nasal cavity). Axons from the receptor cells join into approximately 20 small nonmyelinated bundles (the olfactory nerves). These nerves pass into the skull through holes in the cribriform plate of the ethmoid bone and terminate in the ipsilateral olfactory bulb in spherical synaptic structures called glomeruli.
