• o. bulb — the bulblike extremity of the olfactory tract on the rostral surface of the frontal lobe of each cerebral hemisphere; it is lodged against the cribriform plate through which the olfactory nerves pass.
• o. glands — in the mucosa of the nasal olfactory region; branched tubuloalveolar glands secreting serous fluid; cleanse the mucosal surface, dissolve odor-producing substances.

• o. nerve — the first cranial nerve made up of about 20 bundles and concerned with the sense of smell. The cell bodies are situated in the olfactory mucous membrane of the nose. Nerve fibers lead upward through openings in the cribriform plate of the ethmoid bone and connect with the cells of the olfactory bulb. From there the fibers pass inward to the cerebrum.
• o. neuroblastoma — rare neoplasm, commonest in pups and kittens, characterized by local invasion of surrounding bone.
• o. pit — primordia of the nasal cavities commencing as pits in the olfactory placodes of the embryo. The pits deepen and finally open into the oral cavity as the choanae; the external orifices become the nostrils. Called also nasal pit.
• o. system — includes the olfactory part of the nasal mucosa, the olfactory nerves and the olfactory bulbs of the cerebrum.
• o. tract — a band of white nerve fibers visible on the ventral surface of the brain running caudally from the olfactory bulbs.
